He's served as a common foe, a boss enemy and a playable athlete in some of the sports spin-offs – though he may be finding his true calling with Kart racing. Those extra arms will allow him to throw items and hold onto the steering wheel simultaneously, after all.Honey Queen is the new name being given to the Queen Bee character who first made her debut in 2007's Super Mario Galaxy.
