Nurse Penny is a fun and funky school nurse who wears honeybee earrings and a butterfly smock and carries a ladybug purse. But there's one kind of bug she'd rather not have around . . . head lice! So she calls a special school assembly to talk about those pesky critters—what they look like, how to avoid them, and how to get rid of them. After all, lice can happen to anyone—even the school nurse!
