The uproarious debut from picture book phenom Mac Barnett is a surreal cautionary tale--illustrated by bestselling talent Adam Rex!

Some interesting facts about blue whales: A blue whale is longer than thirty dogs lined up nose to tail. Its tongue weighs as much as four hundred cats. Consequently, blue whales make terrible pets...just ask Billy Twitters. When his parents threaten to teach him responsibility by giving him a whale, Billy isn't worried: 'It's not like you can just have one delivered to your house overnight.' But he's wrong. It arrives via FedUp (motto: 'Delivering Punishment Worldwide'), and it's up to Billy to take care of it!
