Water bomb (object)

Water Bombs are large, cannonball-like objects in Super Mario 64 and Super Mario 64 DS. They are shot out of cannons on the Bob-omb Battlefield course, specifically the unusable cannon on the mountain (along with the one at the start in the remake), and in the Battle Fort stage in the DS remake, falling out of the sky at random. They typically land in the larger field areas of the course and act like large, bouncing water balloons, exploding and dealing damage if they come into contact with the player character. After two hops, the Water Bomb will dissipate the next time it hits the ground.
