A humorous enemy character in later episodes of the "Final Fantasy" series of role-playing video games. It resembles a cactus with branches serving as arms and legs protruding at right angles, and three dots/holes forming a crude face. Agile and possessing machine-gun-like needle attacks, these things can be a pain in the ass if you don't know what you're doing.
