PIG and the Talking Poo

Pig has a huge brown plastic dog poo. (Not one of those long ones that go dry. This one's a curly brown, wet-looking poo, with a little black plastic fly on it.) Pig thinks the poo talks to him (he doesn't think that really - he's not bonkers or anything). But he does miss his poo lots when he loses it - mainly because it reminds him of his dad.
