A series of robberies has disrupted the peaceful life at the Bean Farm. First, food disappears from The First Animal Bank. Then sheets and shirts vanish from a clothesline. By the time oats are stolen from the barn, everyone is suspicious and upset. Soon, the animals even suspect Freddy!
Who, or what, is responsible for the crimes? What is the mysterious white shape in the Great Woods? When the animals get threatening letters demanding food in exchange for their safety, it's up to Freddy to solve the mystery of the Ignormus—even if it means going into the Great Woods alone.
