A gigantic creature was standing in the slimy oozy mud on the river-bank. It was Humpy-Rumpy, the Hippopotamus.
'A gigantic creature was standing in the slimy oozy mud on the river-bank. It was Humpy-Rumpy, the Hippopotamus.' - The Enormous Crocodile
Humpy-Rumpy lives on the river-bank next to the "biggest, brownest muddiest river in Africa," alongside the horrible Enormous Crocodile, who he tries to persuade not to eat the nearby children. He foils The Enormous Crocodile's plan to disguise himself as a tree in order to snap up a juicy child.
The Enormous Crocodile was published in 1978, and was the first Roald Dahl story to feature illustrations by Sir Quentin Blake.
