They looked like deformed, shell-less lobsters, horribly pale and slimy-looking, with legs sticking out in very odd places and no visible heads. There were about a hundred of them in each crate, each about six inches long, crawling over one another, bumping blindly into the sides of the boxes. They were giving off a very powerful smell of rotting fish. Every now and then, sparks would fly out of the end of a skrewt, and with a small phut, it would be propelled forward several inches.
