In Super Mario 64, Mario's goal in this mission is to reach the summit of Bob-omb Battlefield's mountain to fight Big Bob-omb. There are multiple ways that Mario can take to reach him: there is a main path that starts from the first cannon in the level and leads up to the mountain summit (an alcove midway up the mountain can warp Marion to the top), and the cannon at the start can also circumvent most of the travel. There are several obstacles and enemies along the main patch, including Goombas, a Chain Chomp, and Big Steelies that roll down the road spiraling around the mountain. Once Mario reaches the summit, he is confronted by Big Bob-omb, who introduces himself as the "lord of all blasting matter," becomes angry at Mario for scaling his mountain, and challenges Mario to a battle in order to win a Power Star. Big Bob-omb can only be defeated by being picked up from behind and thrown to the ground. If Mario misses and throws him from the summit plateau, he jumps back, claiming that Mario cheated and that he will have to start over again. In order to win the fight, Big Bob-omb must be thrown to the ground three times. Upon being defeated, Big Bob-omb is surprised that he was defeated by someone who seems weak, but acknowledges that his troops could stand to learn from Mario. After that, he disappears and releases a Power Star.

In Super Mario 64 DS, the battle is altered to work for Yoshi, as he is the only character available at the beginning of the game. Since Yoshi cannot pick up enemies the same way Mario, Luigi, or Wario can, Big Bob-omb throws Bob-ombs at Yoshi, who must then grab one with his tongue and throw it at Big Bob-omb before it explodes. Big-Bob-omb says different things in his introduction depending on who's fighting him: he compliments Yoshi for making it to the top despite not having a mustache, he claims that Mario's mustache makes him like a peasant, he commends Luigi for being brave even though he does not look the part, and he notices that Wario's mustache makes him look distinguished and attempts to rip it off for flaunting it so rudely to him.
