Gumball and Darwin love the way they look in their new karate outfits and vow never to take them off.
At school their less than impressive martial arts moves make them a laughing stock.
Mom is concerned that they will become social outcasts, like their father when he went through his “Cotton-Tailed Cavalier” phase.
So after a heart-to-heart talk, Gumball and Darwin agree to grow up, face reality and take off their costumes.
This lasts for about a minute!
When Mom realises that they lied to her,
it becomes a race against time... to get to school before Gumball humiliates himself in front of his classmates.
