Our darling Darwin Raglan Caspian Ahab Poseidon Nicodemius Watterson III, better known as just Darwin, is shocked at how his life changed over the years in our fanart The Amazing World of Gumball Darwin Watterson Surprised Sticker. This character used to be Gumball's pet goldfish, but then he suddenly grew legs and gained the ability to speak. Thus he adapted to life outside of water and was adopted by the Watterson family. Can you imagine the level of his emotional state after such changes?
