It's Halloween, and the five little monkeys are going trick-or-treating with their favorite babysitter, Lulu. Mama reminds her, "Don't lose the rascals!" But in this tale for prereaders, soon those mischievous monkeys meet other costumed friends and decide to try "the best Halloween trick ever!" Will Lulu be fooled? Or will the five little monkeys learn their lesson? As always, Ellen Christelow makes her jolly monkeys the spitting image of human kids, and she includes here a recipe for "Eyeball Cookies."
