The Wicked

"The Wicked" is the eighteenth episode of Season 4 of The Amazing World of Gumball. It is the 134th episode overall.

Synopsis
Gumball and Darwin try to find a single nice quality about their neighbor, Mrs. Robinson.

Plot
The episode begins with Margaret Robinson in the park feeding coffee and prune juice nuts to squirrels. Gumball and Darwin appear and asked to help Margaret, she shakes her head yes. While they fed the squirrels, they suddenly turn savage and attacked Gumball and Darwin and several citizens of Elmore. The Doughnut Sheriff appears and demands who was responsible for this fiasco. Margaret hid behind a tree and blames the boys for this.

As punishment, Gumball and Darwin were made to clean up the trash in the neighborhood as community service. Gumball explains to Darwin that he claims Margaret is evil. Darwin states that no one is evil, but Gumball is not sure.

The next day, Margaret starts to cause mischief again and making people's lives a misery, making Gumball and Darwin suspicious.

The next scene shows the hospital with Margaret and the boys in the baby nursery room. As Darwin explains to Margaret that she should have a good side, she swapped the baby name tags, making their parents fight.

Gumball and Darwin decided to ask Mr. Robinson about why his wife is evil. The boys then found Margaret's photo album, showing her wickedness side in every photo. Margaret gives Darwin a chocolate bar and eats it, but starts choking on it, revealing a toy truck. Darwin asks her to help, but Margaret just smiles evilly at him as she closes her door. Darwin now sees that Margaret is really evil, and he and Gumball decide to stop her.

At the Elmore mall, Margaret puts on a bandana and hijacks a car. She then rampages inside the mall in an attempt to run people over. Gumball and Darwin catch up to her, and pulled the car trigger in reverse, making it drive backwards and crashing into a lamppost. The boys explain to Margaret that there are consequences for her actions.

The Doughnut Sheriff arrives to arrest Gumball and Darwin as Margaret drives away evilly, Darwin yells about justice, and Margaret hits another lamppost, crashes into two gas trucks, which suddenly explode, sending her flying in the air, got hit by a passing airplane, then finally gets run over by an ambulance, ending the episode.
