Bob-omb
A Bob-omb (sometimes called Bomb-omb) is a living bomb character, featured in the Super Mario Bros. series of video games. It can also be an item.
First introduced in Super Mario Bros. 2, where its general habits (walk around for a while, then explode) were made quite clear. In Super Mario Bros. 3, some Bob-ombs have small wind-up keys on them -- if the key is disturbed, they will explode after a few seconds. Otherwise, they will peacefully wander back and forth.
Bob-ombs are the subject of many minigames in the Mario Party series.
Bob-ombs and their more powerful counterparts, Rob-ombs, appeared in Super Mario RPG.
The Bob-omb also appears in the Super Mario Bros Movie.
In Super Mario 64, the pink "Bob-omb Buddies" were introduced in a stage called "Bob-omb Battlefield." They were friendly to Mario and at war with the normal black Bob-ombs. The black Bob-ombs either tried to chase Mario down and explode if they saw him, or they manned cannons and shot water blasts at Mario. The boss character of Bob-omb Battlefield was King Bob-omb.
Bob-ombs have also appeared in Mario Golf: Toadstool Tour, where golf balls impacting on a Bob-omb causes it to explode, sending the ball out in the opposite direction. They also have appeared in Super Smash Bros. Melee as items.
