Robomelon was the best friend of Robocabbage, and doesn't like potatoes. I don't know.
A green watermelon. With a hole that he uses as a mouth.
He would be vital in plans, grabbing him and pretending to throw him at people made them duck, giving you a fighting chance. After the extreme death of Robocabbage, he just stopped talking, and now spends his time in his room, staring at the wall, carving wood. Somehow. He holds it in his teeth and kinda, moves around, but they're beautiful.
