Bob-omb, known in Japan as Bomuhei (ボム兵, lit: Bomb Soldiers) is a walking living bomb enemy that has appeared all along the Mario series. It originally first appeared in the non-Mario game Yume Kōjō: Doki Doki Panic, but was introduced as a Mario character in the western localization for said game, Super Mario Bros. 2. It has two white eyes, a fuse, two legs, and usually has a wind-up mechanism on its backs but is not necessary.
