Bob-ombs are walking bomb enemies from Nintendo's Mario series, first appearing as foes in Super Mario Bros. 2 and later returning in platform games, Mario Kart and Mario Party titles. Their design, a round black bomb body with eyes, feet and a wind-up key, made them instantly recognisable, and short clips of their in-game sounds have long circulated on soundboards and in fan edits. The stomp remains popular because it is instantly readable, funny without words, and fits the fast, joke-driven rhythm of short gameplay videos.
