Sure, he's cute. Of course you can keep him. But heed
these three warnings: Don't ever get him wet. Keep him
away from bright light. And the most important thing,
the one thing you must never forget: no matter how much
he cries, no matter how much he begs . . . never, never
feed him after midnight. With these mysterious instructions,
young Billy Peltzer takes possession of his cuddly new pet.
He gets a whole lot more than he bargained for.
