The Enormous Crocodile by Roald Dahl

The Enormous Crocodile is a beastly creature. He lives in "the biggest, browniest muddiest river in Africa," and he is just about the beastliest crocodile there. Where the Notsobig crocodile eats only fish, The Enormous Crocodile wants to eat everyone in the jungle, from The Roly-Poly Bird to Muggle-Wump the Monkey. But his favourite food of all is a yummy-tasting child...
It's this that makes him leave the river to search out a tasty lunchtime treat, using his "secret plans and clever tricks" - even though the Notsobig One says he's the stupidest croc on the whole river. So will he be successful?
