The Amazing World of Gumball Vol. 4: Scrimmage Scramble

This is the 4th Graphic novel of The Amazing World of Gumball.

Plot
When Anais goes to Darwin and Gumball for help in learning about sports to prove she can beat the new exchange student, things get out of hand when the whole school gets involved in a fake sport that her brothers totally -no, really- know how to play.

Anais is having a hard time dealing with a new exchange student, and decides to challenge him in a sport...only, she doesn’t know how to play any sports. Deciding that Gumball and Darwin will be the help she needs, she asks her brothers to show her how it’s done. Gumball and Darwin don’t want to let her down, but also have no idea what they are doing, and so they decide to invent their own sport to show off how cool they are. This works until the whole school gets drawn into an intergalactic showdown with their made-up sport as the battle field.
