Rob-omb

“Disappear? Maybe later”

—Rob-omb, Super Mario RPG: Legend of the Seven Stars

Rob-ombs are a stronger variety of Bob-omb found in Super Mario RPG: Legend of the Seven Stars. These walking explosives wear purple shoes, and work exclusively for the demented Booster. They can often be found walking in simple patterns in the stairwells of Booster's Tower. Also, Booster himself keeps a personal store of Rob-ombs on his private train to deal with any unwanted visitors. Like other Bob-ombs in the game, Rob-ombs can only attack by self-destructing, destroying itself and damaging an opponent. As such, Rob-ombs should be defeated before they explode. Unfortunately, Rob-ombs often appear in large groups, meaning one of them is bound to self-destruct before they can all be destroyed.

Another variety of Bob-omb with purple shoes, the Lethal Bob-omb, appeared in Mario & Luigi: Partners in Time.
