Gumball is one of the cat people in the family, the first episode " The Responsible ", is when Gumball's Mom, Nicole Waterson, hires Gumball and his fish brother, Darwin, to take care of their sister Anias, but things turn out nasty. Gumball and Darwin have been in EVERY " The Amazing World of Gumball" episode, but not everyone, like Penny, a peanut with antlers and Gumball's crush, Richard, Gumball's dad, or Tina, the school bully T-Rex. Gumball was created in the 2010-2011 period, but not most of the rest. Penny is now Gumball 's girlfreind. Penny is a shapeshifting fairy as of "The Shell".
