the trial (sic.) of the snail

So, this snail is lying on his shell, waving his eyestalks around, and the local constable, a turtle, finds him and turns him right side up.

"There, now," says the turtle, "what's all this, then?"

"Officer, I was robbed by a pair of slugs!" says the snail.

"Can you identify them?"

"Oh, no -- it all happened so quickly!"
