There's no such thing as monsters. Mother and Daddy even said so. But then why is there monster drool on Junie B.'s pillow? Oh, no! What if Paulie Allen Puffer is right -- what if she really does have a monster under her bed? If Junie B. goes to sleep, the monster might see her feet hanging down. And he might think her piggy toes are yummy little wiener sausages!
