The book has also been turned into a play that was staged for children at the Edinburgh Festival in 2002.
A mole discovers a pile of poo on his head and is certain that it doesn't belong to him. He sets out on a mission to discover who it does belong to. His investigation takes him into the world of many animals, as he wanders and compares the pile on his head to the piles that other animals leave behind them. He finally receives some assistance from some flies who help him identify a sleeping dog. Our hero exacts his revenge by doing a mole size poo into the dog's mouth.
