Orange 'n' GreenEdit
In Super Mario Silver Spurs: The Crossover Vacation, Darwin goes with the rest of the Watterson family on vacation. He becomes a companion to Luigi in the same way that Gumball does to Mario. In fact, Darwin even becomes a friend to Bowser Jr.
Darwin also appears in Gumball: Double Trouble as a major character. He has a slight rivalry with Mint Chewers in the game; however, his knowledge of underwater environments helps the group throughout their mission.
Here he appears as a playable character, rival to Godard.
