Sherman is the sweetest, best-behaved pig in the whole wide world. His owner, Adelaide, is positive that bringing him to Ethan's birthday party won't be any trouble at all. Then Marlon performs his magic act at the party, and Sherman -- and all hell -- begins to break loose. Before Adelaide and her friends know it, Sherman is running amuck in the neighborhood, tromping on peonies, swimming in pools, upsetting paint buckets, and disrupting tea parties. Only a yummy chocolate cake can get Adelaide's porcine friend to "Stop, Sherman! Stop!"
