A fireball from the sky causes Noah's home to break free from the Canadian coastline and float away. Now adrift in the Atlantic Ocean, the island runs out of steam in dangerous and freezing waters. Noah is ready to try anything to set the lava flowing again. Elsewhere a ship carrying a collection of animals bound for foreign zoos sinks in the middle of the ocean, leaving many of the surviving caged animals shipwrecked.
The island is beset with territorial disputes. Having won the animals interest, Noah is continuing with his efforts to get them to co-operate as one community. However, Reg, believing Noah to be crazy with his eccentric ways, protests against it with his own idea of each animal having their own individual country on the island. When the two animals both argue over their different ideas, Reg wins. Noah is left by himself. While some of the remaining animals try to sort out their problems, Noah recruits a small band of animals who are assigned certain jobs around the volcano. Meanwhile, all of the animals are finding it difficult to adjust to their new territories after suffering setbacks. They crawl back to Noah eventually realising that he was right about them working and living together as a family.
Noah has a shower with the help of Mammothsbody, who uses his trunk as a hose. Noah explains his intentions to the mammoth of rescuing more animals from Spain as they pass the Iberian Peninsula. But as Mammothsbody prepares to refill his trunk with water, a jellyfish lodges itself in his trunk and is accidentally sucked up! Noah has to rush the distressed mammoth to the infirmary where he finds Rocco lying across the operating table, Woomera impatiently attempting to remove him. Upon seeing the stricken patient, the kangaroo knocks Rocco off the table. Rocco fists the jellyfish from Mammothsbody's trunk. At that moment Salomi enters and Mammothsbody proposes to her, but once again he is rejected as the female mammoth spots the jellyfish. A heartbroken Mammothsbody goes to Problem Walrus to seek advice on the matter but the walrus puts him down, telling him he is 'slow, dim, witty and clueless'. Later the island becomes home to a Russian desman named Sacha.
The island runs aground, and A Lion appears.
Tusker's ability to propel large quantities of paint across the cave walls proves most agreeable with Reg.
Reg decides that his cave dwelling needs a splash of colour and therefore kidnaps the Baby Elephant to fill the vacancy of interior decorator. Tusker's ability to propel large quantities of paint across the cave walls proves most agreeable with Reg yet unfortunately the little elephant's grandfather does not seem to share in this venture. Grandfather elephant successfully rescues Tusker and dunks Reg in the remainder of the paint. Reg, absolutely furious by this, decides to attempt to drop a large boulder on the elephants yet as always it ends in tears for Reg; who ends up running for his life from an out of control 2 tonne boulder!
As the island travels along the South American coast, the Vulture Squadron circles over the island and comes down to land. But the Squadron Leader accidentally flies into the fire ball and as a result is blinded, leaving him unable to fulfil his duties. The injured vulture is carried to the infirmary where Rocco tells him to breathe in some of the volcano's sulphurous fumes to cure his ailment. The Squadron Leader then announces his resignation. Things get worse for the squadron when Him announces that he wants to be a bear so he can attend Noah's Bear Evening, an event which he holds regularly for the other bears (Ursula and Panda). Noah advises Him to seek out Ursula who asks Panda to demonstrate her 'ferocity' for the hapless vulture. Elsewhere a stream has been diverted by a large log causing the island's water supply to flow in a different direction. Noah, Woamera and Rocco attempt to move it but fail. Grandfather Elephant is 100 years old and informs the rest of the animals he will be leaving the island. He tells Mammothsbody that he has 'a warm heart' who says to Salomi it is 'the nicest thing anyone has ever said to me' before proposing again. As usual he is rejected. Noah then comes to ask the ancient elephant to remove the log. Grandfather Elephant is not attending the Bear Evening as he is not a bear and so spends some time playing with Tusker on the beach. This involves burying a visibly astonished Problem Walrus in sand. Bear Evening is proving unsuccessful as Him upsets the peace and Ursula lunges at him from across the table. Sacha is upset at being unable to attend and plans a circus performance to coincide with the event. Lion? is somewhat bemused to find himself the main attraction and when Sacha encourages him to be fierce, he takes it literally and threatens to eat the desman. Sacha's pleas are heard by Salomi and Mammothsbody who are out for a walk on the beach. Salomi calls for help. Noah and the other Bear Evening attendees hear the commoti
It is a normal day on Noah's Island until the silence is broken by the discovery of some dolphins on the beach. The animals assist Woomera, who gets a personal attachment to the situation, in enticing the dolphins back to the sea; alas the next day the dolphins have been washed up on the beach once again. By this time the entire island's population has fallen ill with the 'meese': a contagious virus similar to measles. So with the majority of the animals quarantined in the infirmery Woomera has no choice but to save the dolphins herself. All night she tries but her efforts are in vein, for at dawn she confides in Noah that 'they're all dead.' With a great sense of personal loss Woomera decides to leave the island and asks Noah to steer the island as near to South America as possible so she can swim ashore. When Rocco gets wind of Woomera's plan he races to the beach to stop her. But he is unfortunate enough to be in the firing line of a coconut, accidentally rolled off a cliff above by Sacha and his little cockroach friend. Knocked unconscious by this heavy fruit, Woomera turns to see Rocco face down in the surf. In an attempt to turn back to assist, from some offshore rocks she slips into the ocean and is taken ashore by yet another dolphin. She pulls Rocco from the water and realises her place is on Noah's Island.
In an attempt to reach the legendary Diamentina as soon as possible Noah decides to take a short cut around Cape Horn; an area of sea renounded for its vicious storms. During the passage through this treacherous stretch of water a massive wave crashes through the island and extinguishes the firebowl rendering the island merciless to the ocean currents. The animals are furious with Noah for not only has their only power source been lost but Mammothsbody has been seriously injured from the storm. Noah now a broken bear wanders off and Reg, never missing a trick, takes over and self-elects himself as captain. The island is drifting further and further south and the temperature is dropping and when snow starts to fall it is a welcome relief for the animals that Mammothsbody has recovered and Salomi has accepted his proposal of marriage. Whereas Noah, who is trying to square things with Reg, is far too occupied to bless the happy couple. Reg threatens Noah that he will 'set his doggies' on him if he doesn't leave but Noah isn't giving up that easily and with a little assistance from some visiting penguins Reg relinquishes his post and Noah returns to his rightful position.
Noah's Island has ended up floating very near to Antarctica which causes a rather chilly unpleasant environment for the island's animals. With snow and ice everywhere the animals all turn to Reg with his human genius to make them a fire. After some subtle persuasion Reg agrees and makes the animals a large fire in his cave. Meanwhile Sacha and Carmon have been exploring the winter wonderland and come across an uncovered egg. Intrigued they take the egg to Reg's cave where the fire hatches it. Nab, one of the only animals present at the hatching, recognises it instantly as a 'Do-Da', a famous extinct bird. Whilst these events are happening Noah, Sacha and Sacha's nephew (the baby vulture) are hot on the trail of a shooting star which has landed and become lodged at the highest point on the island. Also down in the Mammoth cave the long awaited wedding of Salomi and Mammothsbody is well underway with the majority of the island's animals present. One of the procedures at a mammoth wedding is to 'stomp' around for several hours and the animals reluctantly respect this ancient tradition yet the vibrations cause the ice above ground to crack. This in turn dislodges the shooting star from its resting place and causes it to roll down the hill side at tremendous speed, fortunately right into the firebowl freeing the island's energy once again. Enjoy
Coming away from the Antarctic Coast, the Island is getting closer to Diamantina, but Salomi is worried that she will die when they reach the paradise, which frightens Mammothsbody. Meanwhile, a cargo plane crashes on a nearby reef, and Noah and The Problem Walrus swim out to investigate. They rescue Gertie, a female gorilla who was born and raised in a zoo, and bring her back to the island, but Gertie's loud and bossy personality soon begins to annoy the other animals.
Noah's Island has come alongside the great continent of Australia and Woomera is feeling homesick. Tired of being bossed around by 'a blinking gorilla' named Gurtie, who is orchestrating a mass replanting of the island from an Australian oasis, Woomera decides to check out her old stomping ground and heads off into the outback. After being challenged by Gurtie that bandicoots have now become extinct, Woomera sets off on a mission to find one but instead meets a wombat (Wommie). Wommie informs Woomera that the bandicoots have all been eaten by the Bunyip yet she is undeterred by this and is insistent on finding one. Meanwhile back on the island Jasper has spotted a tornado heading directly for them; it is then Noah's task to bring Woomera back to safety and so the island can resume its journey. Woomera is successful in finding her bandicoot and the gang leave Australia in one piece.
An approaching tidal wave threatens the Island, so Noah sends the Vulture Patrol to search for another island that they can hide behind until the wave passes. The vultures succeed in finding a suitable island, only to discover that it is populated by hundreds of green parrots that refuse to heed their warning of the impending tidal wave.
Rocco is very proud on the day in question as his first 'silver hair' has appeared on his back. Being a Silver Back Gorilla it is a momentous occasion for him. Meanwhile Reg has become sucked into a whirlpool that has appeared on another end of the island. Reg is fascinated by his discovery of a giant clam containing a huge pearl at the bottom of this watery apparition. The rest of the animals attempt to save him but all inevitably fall in as well. With a little assistance from Noah and Salomi, the stranded animals are rescued. However, Mammothsbody, on the escape from the whirlpool's depths, strangely pulls out and eats Rocco's silver hair.
Wombat (Wommie), a new member of the island has made a didgeridoo and its strange sound is attracting butterflies from everywhere. When Reg discovers this strange instrument's talent he relieves Wombat of it and takes up butterfly collecting. He soon discovers that Noah's Island is about to pass an uninhabited island which is likely to be a great chance to hunt down some new specimens to add to his collection. After tricking Rhino into adjusting the firebowl valve, Reg swims ashore, with Sacha and Noah in hot pursuit of him. The trio shortly discover that the only indigenous life on this island is a formidable, meat eating plant that seems to cover most of the island floor. Sacha is the first to fall victim to these evil plants' dinner plate but Noah comes swiftly to the rescue, swinging from the trees above in a Tarzan re-enactment to rescue his little friend. The other animals soon realise that the three are missing and turn back to the island and rescue them.
Whilst Reg is mucking around on the beach, an old foe of Mammothsbody's surfaces: the shark. Squadron leader saves Reg from the wrath of this vicious marine creature but is fatally wounded and is convinced his time is up. With the Squadron Leader's impending death he decides that a competition must be held to determine who will succeed him as leader of the vulture patrol. A variety of contests take place including "Whelk Slurping" and "Pin the Tail on the Wildebeast", who is actually Mammothsbody (who is terrified that the vultures will "eat" him). Even though Reg is appointed as chief judge, many of the vultures end up in the infirmary. Then through a strange course of events 'Baby Chick Bird' wins and becomes designated the new squadron leader. After a brief speech at his inauguration ceremony the weak, old 'Squadron Leader' realises he still has "much to teach" his vulture patrol and conveniently rearranges his appointment with the Grim Reaper.
A heat wave passes over the Island and the animals all try to keep cool. Noah and Wommie rescue a pangolin who is adrift on a log and bring him back to the Island, where he immediately befriends Carmen the Aardvark. After Carmen and the pangolin eat the queen of a termite colony, Sacha offers himself as a replacement queen, but the termites capture him and imprison him in their nest. Upon hearing what has happened, Noah sets out to try and rescue Sacha. Meanwhile, the strong heat causes Woomera to faint, and Rocco fears that she may die of heat stroke...
The Island has some univited visitors in this episode. Snakes arrive to wreak havoc by biting nearly every animal they meet. With the casualties mounting Noah looks to the vulture patrol to bring a mongoose from the mainland to help them. The vultures come up trumps and locate such a mongoose who then treats the bitten with his herbal medicines. Noah however gets spat at by the snake ring leader (a cobra) and is blinded. Luckily for him the effects are only temporary and his sight returns. The snakes are forced into retreat. Meanwhile Mammothbody fights the shark using problem walrus as a club. the snakes are loosed onto the sharks tail leaving island for good.
The Island floats through oil-polluted waters, and as the beach becomes covered in oil, Noah is stuck with what to do. Goosey and Salomi suggest that they find a golden mole, a rare animal that is rumoured to have magical powers and never fail in navigation, and Noah, Sparky and Sacha travel ashore to the Arabian desert to find a golden mole.
The Vulture Patrol returns from a scouting mission on the east African coast and tell Noah that they saw some animals trapped in a long-abandoned zoo. Rocco and Ursula are sent out to help the animals, and Rocco recognises the zoo as the one he was born and raised in. During the rescue mission, Rocco is reunited with Imshee, a warthog he knew when he was a child. Meanwhile, a stampeding herd of gnus find their way onto the Island and wreak havoc.
The Island travels past Madagascar, and Ursula decides to do a good deed to redeem herself for past mistakes. Noticing that a portion of forest has been cleared by humans, Ursula steals a coconut that Noah planned to give to Rocco and Gertie as a wedding present and travels to the mainland with Chang and Mammothsbody to plant it. Upon arriving though, the animals meet Calanor, a devious aye-aye who hypnotises them into doing his bidding. Calanor commands the hypnotised Mammothsbody to take him to the Floating Island, where he plans to overthrow Noah as its leader, and things get worse for Noah when an enormous swarm of locusts descend on the Island and set about eating all the plants.
As the Island passes by Mauritius, Do-Dah is feeling depressed and frustrated about never meeting any other dodos in his life, and is in denial about his species' extinction. The Problem Walrus suggests that Do-Dah should visit Mauritius to find out more about his kind, and Sacha and Wommie accompany Do-Dah on his trip. Meanwhile, a sea turtle washes up on the beach and asks Noah and the Islander's help in defending her newly hatched babies from a hungry Komodo dragon.
The Island approaches the final leg of its journey, and Diamantina is only a few days away. However, a fire breaks out on a nearby island inhabited by giant tortoises. Noah commands one final rescue mission and the animals evacuate all the tortoises from the burning island. Afterwards, the Island finally reaches Diamantina, and the Islanders waste no time in disembarking onto the promised land. Upon arriving, the first animal they meet is Gorm, a woolly mammoth who turns out to be Salomi's long-lost father.
The Animals settle into their new life in the promised land of Diamantina, but all is not well. Diamantina is plagued with earth tremors, one of which causes a rock slide that leaves Gertie trapped in a cave, and after Gorm confesses that Diamantina floods during the night of a full moon, the other animals begin to blame Noah for leading them to a place where they're always in danger. Elsewhere, Chang discovers a cave full of beautiful jewels, but when Ursula finds out about the cave they argue over ownership of the jewels.
The Animals stop listening to Noah and turn against him in the aftermath of the flood. Meanwhile, Diamantina's other residents, a race of prehistoric frogs, learn of the inhabitants of the floating Island, and seeing them as invaders, they prepare to fight back...
Noah and Gertie decide to set off on the floating island to find mates for the other animals so their community can grow. For their first mission, they travel to Africa to find a mate for Reg, bringing back a boisterous female baboon named Rita. Gorm is outraged by Noah and Gertie's plan, believing that more animals coming to Diamantina will ruin his peace and tranquility. Queen Abront advises Gorm to kill the "Invaders", starting with Reg.
Gertie gives Sacha the job of Diamantina's "Newshound", in which he has to travel around the community and report current and upcoming events, but he ends up spreading gossip and secrets that he overhears. Meanwhile, Noah, Gertie and Wommie go to Australia to find a mate for Woomera, and Reg steals all of Diamantina's bananas to impress Rita, causing upset among the community's primates and further angering Queen Abront and the frogs.
Wommie the Wombat is appointed as Diamantina's law enforcement, but he abuses his newly gained authority by arresting animals for the smallest of offences, such as Mammothsbody sucking his trunk and Carmen eating ants without a "licence". Meanwhile, Chang and Ursula find a strange man-made machine washed up on the beach, and upon discovering it has a camera and human voices coming out of it, Noah orders to have the machine destroyed, believing that it will lead humans to Diamantina.
Salomi senses that Diamantina will flood again, so Noah orders Sacha to spread the word of the next flood. Rocco and Gertie plan to build a rock wall in front of their cave's entrance to protect the animals from the flood, while Noah and Nab struggle to find enough lava stones to fuel the Fire-Bowl. When Noah finds out what Rocco is planning he sets out to stop the wall from being built and convince Rocco that the wall won't protect them.
Noah and Gertie go back to Africa to find a mate for the Valve Rhino, but because the Rhino has charged off into the forest, they ask Gorm to push the valve system in the Fire-Bowl. The Rhino wanders into Queen Abront's cave, and Rocco and Woomera venture in to find him, but get lost in the tunnels. Meanwhile, Galleo eats the lice Sacha was collecting for his insect circus, so Sacha believes that a monster is on the loose and sets out to find more lice.
An enormous iceberg floats by the coast of Diamantina. The animals who are more used to colder climates, such as Noah and the Problem Walrus, are delighted by the sudden cold snap the iceberg brings, but everyone else tries to escape the cold by sleeping in the Fire-Bowl chamber. Upon discovering that there is a deep crevice within the iceberg, Gorm and the frogs devise a plan to trap the animals inside, so when the iceberg leaves it will take them with it.
Gertie takes up the hobby of weaving raffia. Rocco is initially annoyed by the large amounts of raffia in his cave, but upon noticing the substance's strength, he comes up with the idea to construct a chair-lift that goes across Diamantina using the raffia as a cable line. Most of the animals are supportive of the idea and help Rocco set up the raffia cable, but Gorm is once again angered that the animals are ruining his paradise. When Reg and Rita tell Queen Abront what is happening, she sends Reg to sabotage the construction of the chair-lift.
Boredom sets in to the residents of Diamantina. The frogs and Reg set off to find the very rare Diamantina Rose, which only grows once every 100 years. Sacha meets the frog he saved a while back, and is asked to teach the frog some circus tricks.
The animals take pieces from Diamantina's coral reef to help Gertie decorate her cave, but the removal of coral from the reef has unexpected repercussions. Noah joins Sacha's newshound team to head spread news faster.
Earthquakes are becoming more frequent in Diamantina. Gertie realises that Diamantina is not a safe place to raise her unborn baby, so despite Noah's protests, the Animals prepare to leave Diamantina for good. Ursula is elected as a new captain.
