The Monster Beneath the Earth is the ninth Event Match in Super Smash Bros. Brawl. The player begins on Castle Siege as Ike facing two Diddy Kongs. If the player does not defeat both Diddy Kongs before the stage moves to the third level of the castle, the player must also face a giant Donkey Kong, which usually knocks out the player in one hit.
