Here Comes The Poo Bus by Andy Stanton
All aboard, all aboard! But beware, this isn't any ordinary bus. Oh no. Uncle Toad may seem a friend as he collects the insects for a special trip on his bus of poo, but it's just a cunning ruse. Because when they reach the seaside, it's gobble, gobble, munch munch as greedy Uncle Toad gorges himself rotten. Eeuugggh.
