Bob-omb Battlefield

The Bob-omb Battlefield is the first course in Super Mario 64 and Super Mario 64 DS. The player character can enter the course through the painting in the far left room on the first floor of the Mushroom Castle, and the door into the room does not require any Power Stars to open. The Bob-omb Battlefield is the grassy battleground of a war being waged between the black-colored Bob-ombs, led by the Big Bob-omb, and the pink-colored Bob-omb Buddies.

Layout
The setting of the course takes place on and around a mountain, split between the territories of the two Bob-omb races. The player starts in the Bob-omb Buddies' territory, far off from the mountain in an area with two Bob-omb Buddies and a cannon that is available to use after the player has collected the first Power Star, along with a couple of crates and Goombas farther ahead. To the left of the starting area are a few Bob-ombs and a gate that has to be opened by pressing the Purple Switch on the other side of it, providing a shortcut should it be opened. Additionally, several iron balls roll down the slope and collide around this area. Going up the bridge from the starting area leads the player into a field with several large rocks, Goombas, a Koopa Troopa, and a Chain Chomp. Several water bombs fall into this area, damaging the player character if he comes into contact with them. Crossing the teetering bridge ahead brings the player into the Big Bob-omb's territory.

To the left of the bridge is an area with a couple of Goombas and several stumps, in the middle of which is the Star Marker for this course. Up the short set of stairs is a large field with many Bob-ombs and a cannon, along with water bombs falling from the sky to attack the player. At the end of the field is a path leading behind the gate from earlier. Going up the stone path leads into the base of the mountain, which has two iron balls (or three except for the first Star in the original version) rolling around in the crevice. The way up the mountain is a spiraling pathway with iron balls constantly rolling down it and gaps the player has to jump over. The player can also use a Warp Point, located in the small cave the iron balls roll out of, to instantly travel up to the top of the mountain. At the top of the mountain lies either the Big Bob-omb during the first mission, the flagpole during the race against Koopa the Quick during the second mission, or nothing at all during any other mission.

Also on the course is a floating island that does not appear to be controlled by either territory. The island contains a red block containing a Wing Cap/feather, a yellow block containing a Power Star, and a cannon that can be used to collect the rings of coins floating in the air.
