The Story of the Little Mole Who Went in Search of Whodunit

A 1001 CBYMRBYGU.

Now this is a book that would stir them up. Little Mole discovers poo atop his head. Who did it? It's not the horse. It's not the rabbit. It's not the goat. It's not the cow. Little Mole resorts to going to poo experts, flies, and discovers the culprit....It's the dog. One bad act deserves another and Little Mole has his revenge.

Here's a taste (sorry):

Then Little Mole asked
a horse who was grazing
in the field, “Did you do
this on my head?”

“Me? No,” the horse
answered. “I do mine
like this.” (Bump! Thud-thud-thud!
Thump!—five big, fat
horse droppings thundered
down, just missing
Little Mole.)
