Every morning a very large and very snappy crocodile shouts this selfish message: ‘Stay away from my river! It’s MY river! If you come in my river, I’ll eat you all!’ The animals in the forest don’t know what to do. They are frightened of the crocodile. Even the fish, tadpoles, frogs, crabs and crayfish stay out of the water. Until one day the creatures are woken by a loud groaning sound which turns out to be the selfish crocodile in a lot of pain, and the smallest of them all, a little mouse, finds a way to solve their snappy dilemma!
