A Bob-Omb is one of the (somewhat) common enemies in the Mario games, first making their appearence in Super Mario Bros. 2 (Super Mario USA in Japan) and appearing in almost every Mario game ever since. It is also one of the many weapons in the Super Smash Bros. games, where they can be potentially very dangerous and have been known to fill the contents of a Party Ball. They can also rain down on players when a Sudden Death match takes too long. Not to be confused with #524, Roggenrola
