There's a strange thing lurking in Peter's bathroom! It looks a bit like a frog - but then again, perhaps it's a pig? Maybe even a dragon? It is green and slimy, and frankly it's getting in Peter's way. No one else seems bothered by it - but it's getting on Peter's nerves. He's awlays wanted a pet of his own, but really! The thing will have to go! Trouble is, will it want to . . ?
