DeGroat's latest clever caper starring Gilbert the opossum (Roses Are Pink, Your Feet Really Stink) finds the fellow on an overnight trip to Camp Hi-Dee-Ho. He stoically refuses to pack his teddy ("Sleep-away camp is for big kids") and puts up a brave front when big-mouth fellow camper Lewis trots out some typical camp-related taunts, announcing that a ghost haunts Hi-Dee-Ho and calling the lemonade "bug juice." Around the campfire, after an older kid relates the tale of the alleged ghost, Lewis sneaks up on Gilbert and scares him with a loud "BOO!" In the cabin after lights-out, the hero tightly hugs his teddy (which his mother has slipped into his sleeping bag). DeGroat suspensefully prolongs a nighttime trip to the outdoor bathroom along a dark path lined with threatening-looking trees and, in a signature twist, Gilbert gets a chance to give Lewis his comeuppance. Numerous droll particulars, including Gilbert's Martian-and-spaceship–patterned pajamas and the likable lad's hyperbolic facial expressions will keep readers coming back for more. Those anticipating—with or without some anxiety—an inaugural camp experience especially will revel in this realistic yet reassuring visit to Hi-Dee-Ho. Ages 5-8. (May)
