When a crocodile captures Mrs. Chicken and takes her to an island to fatten her up, clever Mrs. Chicken claims that she can prove they are sisters and that, therefore, the crocodile shouldn't eat her.
Chicken wants to help Earl and Pearl plant their pumpkins, but she only manages to get in the way, until grasshoppers invade the pumpkin patch and Chicken is the only one who can stop them.
Still yearning to be seen as heroes, Wolf, Shark, Snake, and Piranha set out to rescue ten thousand chickens from a high-tech cage farm--but one unexpected problem is Mr. Snake himself, also known as "The Chicken Swallower.".
