Cucumber was a laid-back, cool, and anthropomorphic cucumber who Orange thinks is very cool. Cucumber is later killed by Knife. He later appears in the episode Frankenfruit as the left leg of of Frankenfruit. He wasn't wearing his jacket nor his jewels. He was then killed along with most of the other parts of Frankenfruit by the Halloweenie. In Comedy Roast!, look closely at 0:13. He is in one of the chairs, so he is still alive.
He reappeared in Frankenfruit as Frankenfruit's leg, although this time he was without the jacket, the necklace, and the tattoo. He retained his sunglasses though but he does not speak. He was then killed by the Halloweenie.
