Bob-omb Battlefield

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 Mushroom Castle and the door into the room does not require any Power Stars to open. Bob-omb Battlefield is the battleground of a war being raged between the black-colored Bob-ombs, lead 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 will be available to use after the player has collected the first Star, along with a couple of crates and Goombas further 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 large boulders will roll down the slope and collide around this area. Going up the bridge from the starting area will lead the player into a field with several large rocks, Goombas, a Koopa Troopa, and the only Chain-Chomp in the game. Several Water Bombs will fall into this area, damaging the player character if they come into contact with them. Crossing the teetering bridge ahead will bring 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 log 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 will lead into the base of the mountain, which has two or three large boulders (depending on the Star chosen) rolling around in the crevice. The way up the mountain is a spiraling pathway with large boulders 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 boulders roll out of, to warp up to the top of the mountain. At the top of the mountain either lies the Big Bob-omb during the first Star, the goal during the race against Koopa the Quick during the second Star, or nothing at all during any other Star.

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