Game & Cactus is a Game & Watch, and the older sister of 3.14 and 4.13. She first appears in 3.14: A Pie In The System, as the Game & Watch to be created just before 3.14. She later gains a larger role in Paper 3.14 as a partner.
Game & Cactus looks like a small cactus that is completely black with a white outline. However, in Paper 3.14, she also gains a pink bow on the top of her head and a cute facial expression, with pure white eyes.
