Mushrooms are very special creatures: they are available in thousands of colors and shapes. They grow in the forest, under trees and on food. Tobi goes with mushroom expert Annett in the forest to collect mushrooms. He checks which mushrooms are edible and which are poisonous - and how to recognize them. That's important, because some mushrooms are even deadly! Then Tobi sets out to find the most expensive mushroom in the world: the truffle.
