Readers take a Graveyard School class trip to the museum with Park and his friends. Sneak away from the others. Rattle the dinosaur bones, jump out and say "Boo!" to the museum guard, play a little hide-and-seek. But don't go near the mummies. One of those mummies isn't wrapped right, as Park found out just before he disappeared.
