The episode begins with Gumball unveiling his newest invention to Darwin, the Entertainernator, which was designed to cater to the short attention spans of kids. As he demonstrates how it works, Nicole bursts into the room with Richard and Anais. They accuse Gumball and Darwin of taking twenty dollars from Nicole's purse, using Richard's toothbrush, and stealing Anais's Daisy the Donkey doll. Gumball and Darwin deny these claims, but they are punished nonetheless by staying in their room until they confess they did it. The rest of the family go to the museum, leaving the boys behind.
