Darwin

Darwin Raglan Caspeon Ahab Poseidon Nicodemius Watterson III, was once Gumball's pet fish who grew legs and became part of the family. It appears as Darwin had his feet since he was very little, as seen in a photo in "The Hero". It is revealed that he was a Christmas Gift and had been adopted several times as he states "You're not one of my dads" to Chris Borris in "The Burden", he appears to be somewhat of a Lady's Man and is a ten year old mutation of a goldfish and suckerfish.
