Bob-omb Battlefield (ボムへいの せんじょう Bob-ombs' Battlefield?) is a world in Super Mario 64 and its remake, Super Mario 64 DS. This world serves as the first world in these games as Mario does not need any Power Stars to enter. It is located on the first floor of Princess Peach's Castle, through the door on the far left. Bob-omb Battlefield takes place in a grassland area with many trees. It contains several mountains and hills which can be climbed. The ruler of this land is King Bob-omb, who sits at the top of the mountain in the middle. The Bob-ombs are having a war with the Bob-omb Buddies, who are your friends, so you will have to stop them from destroying everything. There are several Red ! Blocks (? Blocks in the remake) and six cannons in the level. It is impossible to fall off the course here. However, in Super Mario 64 DS, it is possible to perform a glitch by shooting at the bottom tip of the island with Mario's Wing Cap. Doing so will cause the player to go high into the air and from there can go out of the level's boundaries, losing a life. Common enemies here include Goombas, Bob-ombs, and a Chain Chomp (the only one in the game).


At the beginning of the level are the Bob-omb Buddies, who will give you access to the cannon right next to them, the cannon will allow you to go to higher places, such as clouds.

Right after them, you will see a bridge, which the Goombas are guarding, and also a huge Chain Chomp that's guarding a star. All around are Bob-ombs that will blow up all over, and in the middle is a mountain with boulders coming down it.

Koopa the Quick will also offer to race Mario to the top once King Bob-omb is defeated by Mario. The last level of Bob-omb Battlefield is where Mario has to beat the Chain Chomp you have seen in all the other levels. To beat it, one will have to ground pound on its peg. Once the peg is totally in the ground, the Chain Chomp will be freed, and it will give you its Star. There are several Wing Cap Blocks and six cannons in the level.


The level titles and numbers correspond to the original Super Mario 64 unless otherwise noted.

Star 1: Big Bob-omb on the Summit

Mario and King Bob-omb.

To collect the first Star of the game, Mario needs to advance throughout the course and scale the mountain until reaching the top of the summit. There are several obstacles and enemies on his way, including Goombas, a Chain Chomp, water bombs, and Big Steelies which roll down the path. Here, he encounters King Bob-omb, and the two start battling one another. In order for Mario to defeat him, he has to go behind him and lift him up to slam him to the ground. King Bob-omb then makes a single bounce and gets back up. Mario must repeat this step two more times in order to fully defeat King Bob-omb to gain his first Power Star, allowing him to gain access to the top-right room with Princess Peach's Slide and Whomp's Fortress.

In Super Mario 64 DS, the battle is changed as Yoshi is the only character available at the beginning of the game. This makes King Bob-omb not having to be picked up in order to be defeated and rather more must be defeated by Yoshi licking the Bob-ombs he summons and throws it at him three times before they explode in Yoshi's mouth to gain the Power Star. He also bounces more than once after being hit, unlike Super Mario 64 where he only bounces once and then gets up. When playing as Mario, Luigi, or Wario, they can throw Bob-ombs back at King Bob-omb three times.

Star 2: Footrace with Koopa the Quick

Mario and Koopa the Quick.

Once Mario has defeated the Big Bob-omb, he is able to have a go at Koopa the Quick. He will challenge Mario to a race, to the top of the summit. Talk to him to start the race, and head of. Winning the race will grant Mario another star, but the use of the Wing Cap or the cannons will have him accusing Mario of cheating, and the race will have to be done again, just like when racing the Big Penguin in Cool, Cool Mountain. However, any other shortcuts, like the warps, are allowed in this race.

This mission is pretty much the same in Super Mario 64 DS. However, there is a slight change. Koopa the Quick will only want to race against Mario himself. Since Yoshi is the only character available at the time, Yoshi must take a Mario Cap and then race against Koopa the Quick. If Yoshi loses the cap during the race, Koopa the Quick will wonder where Mario is and won't relinquish the Star. If the player regains their Mario Cap and wins the race, Koopa the Quick will act like Yoshi lost. A very useful shortcut in both versions is, before the race starts, the player steps on the switch that opens the gate, and then goes through it during the race.

Star 3: Shoot to the Island in the Sky (N64 only)

Shoot to the Island in the Sky.

This is the third challenge in Bob-omb Battlefield and is exclusive to the Nintendo 64 version. This level requires Mario to use cannons for the first time. Speaking to any of the Bob-omb Buddies in the field opens up the hatches that cover the cannons, and then Mario is able to climb down, aim himself anywhere he wants to, and blast off into the sky. The objective is to get to the big floating island in the sky, and collect the Star hiding in a yellow Exclamation Block. Getting to the island can also be achieved by utilizing the Wing Cap.

Star 3: Five Silver Stars! (DS only)

Yoshi collecting one of the Silver Stars on the tree.

This mission in Bob-omb Battlefield is exclusive to the Super Mario 64 DS remake and can be played as any character. This mission has some differences, including a Chain Chomp running on the loose and Silver Stars in various locations. They are located:

  • Inside of a Goomba with Wario's Cap.
  • Inside of a Goomba near a tree near the cannon.
  • On the chain of the loose Chain Chomp.
  • On top of a tree at the beginning of the level.
  • Hidden inside of a patch of flowers at the far end of where the bricks are located.

Star 4: Find the 8 Red Coins

Yoshi running to the Red Coin.

In this mission, Mario has to obtain eight Red Coins scattered among the course. They are located in the following areas:

  • The first one is located directly above the moving platforms at the start of the course.
  • The second one is located on the stump which the Chain Chomp is stuck to.
  • The third one is located on a small hill near the Chain Chomp and the Koopa.
  • The fourth and fifth ones are located next to the Star Marker for this mission and the fifth mission.
  • The sixth one is located near the top of a slope leading to the mountain.
  • The seventh one is located on top of the tree on the floating island.
  • The eighth and final one is located in a small area where the ground ! Switch is located.

Once Mario has collected all of these Stars, he obtains a Power Star where the Star Marker is.

In Super Mario 64 DS, this mission has been moved to be the sixth mission.

Star 4: Big Bob-omb's Revenge (Nintendo DS version only)

Luigi lifting King Bob-omb.

For this mission, Mario has to fly through five rings of coins in the air using the Wing Cap and collect all five middle coins of the rings to make the Power Star appear. Taking off from the floating island, he has to use the Wing Cap and shoot himself from a cannon to have enough speed to hit all the rings, as well as being able to fly upwards. The Power Star appears in the meadow near the Star Marker. It is also possible to use the cannon on its own to go through all the rings.

Star 5: Mario Wings to the Sky

Mario flying.

After unlocking the Wing Cap (or the Question Blocks in Super Mario 64 DS) from the hidden level in the hallway, what the player needs to do here is to get the Wing cap (or a feather in the DS remake), get to the island in the sky, and get into the cannon. The player must control Mario's flight through each ring of coins. Mario must collect the Coins in the center of the Coin Rings. Once done, the Star will appear. It is possible to get the Star without the Wing Cap (and without activating the Wing Cap Switch) via the use of the Cannon on it's own, but this takes good aiming and can't be done in one try.

Star 6 (N64) / 7 (DS): Behind Chain Chomp's Gate

Mario ground-pounding the post.

This is the sixth Star in the Bob-omb Battlefield, and it is one of the easier ones to get. The player has to free the Chain Chomp by stomping on its post three times. If the player frees the chain chomp, they will get unexpected help in getting this Star. A glitch is to hold a Bob-omb near the bars and wait for it to explode. The force of the explosion will push Mario inside the gate.

In Super Mario 64 DS, this mission has been moved to be the seventh, and there are several alternatives to getting the Star normally. If Luigi uses his invincibility power-up, he may simply walk through the bars to obtain the Power Star and Wario can ground pound it once, because of his weight. It is possible to collect the Star during the third mission (since the Chain Chomp has been moved to the adjacent field)

100 Coin Star

In this mission, Mario has to collect one hundred coins in total. There are many coins in the sky, which can be accessed from the floating island. The eight Red Coins are useful to collect, and Goombas and Bob-ombs are walking about. Running around the wooden posts near the eight Red Coin Star yields five coins each as well.
