Did you know that wombats poo in cubes and that mice can drop up to 75 pellets of poo a day? Do you know which animal’s poo is sparkly like glitter? And which civilised animals always poo in the same spot, a bit like using their own toilets?

With this fun and slightly irreverent book adapted from the bestselling board game, little readers can laugh while they learn all about different animals – specifically, how they poo!
