Nana is having a clear-out and Sam is helping her carry some heavy boxes to the car to take to the school jumble sale. Harry tries to lend a hand, but to his dismay, discovers that he isn’t strong enough! A trip to Dino World is called for to find the solution to Harry’s predicament, and he’s motivated even further when he realises that he needs to be stronger to help Nancy Nanosaurus lift Clown Mountain to retrieve something that has rolled underneath. It’s not long before the Dinos are putting Harry through his paces in the Dino World gym and he’s ready to try his luck on the Dino-Meter Strength Tester. With their new-found strength, Harry and the gang manage to shift Clown Mountain for Nancy before heading home to help Nana with those boxes.
