Mr. Miggles was Maggie's cat. He was hit by a car and died, but Curtis used his new Resurrection power to bring him back to life. He later turned into a zombie who infected Maggie. When Curtis became trapped in Maggie's house, the gang came to his rescue and Simon caught Mr. Miggles under a blanket. However, neither Curtis, Kelly, Alisha or Rudy wanted to kill him, so they took him back to the Community Centre in a box. He later escaped and infected some Cheerleaders.
The gang forget about him, and have to run back to kill him. It is revealed on Twitter that Kelly had to kill him.
