Bob-omb Buddy

Bob-omb Buddies are helpful characters in Super Mario 64 DS. If you talk to one, it will help you in a variety of ways: it will prepare a cannon for you, show you the locations of the Eight Red Coins, or show you where player caps are.

All worlds with cannons have a Bob-omb Buddy somewhere in the map, and when the star for collecting the 8 red coins in the map is selected, a Bob-omb Buddy will be found near the start of the world, or the coins, to tell the player where they are.
