'A perfect animal double-act.' (The Times, Book of the Week)

SPLASH! A Mysterious Thing lands in Rabbit and Bear's peaceful summer lake.

Is it exciting, or terrifying? Is it a tiny fluffy owl, or a huge hungry monster? And has Rabbit finally met a creature with worse habits than himself?

Rabbit's SURE he can solve this mystery. But when he accidentally turns the Best Day Ever into the Worst Day Ever, he needs Bear's help ...

From novelist and playwright Julian Gough, and the winner of the Roald Dahl Funny Prize, Jim Field, this is a tale of friendship, acceptance, and what you can do with blueberry poo.
