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 several obstacles and enemies Mario may encounter along the main path, including Goombas, Bob-ombs, a Chain Chomp, and Big Steely-like cannonballs 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 for a Power Star. Big Bob-omb can grab Mario and toss him if Mario approaches Big-Bob-omb at the front. Big Bob-omb can only be defeated by being picked up from behind and thrown to the ground. If Mario throws him off the summit plateau, he jumps back, stating that Mario cheated and will have to start over. Mario must throw Big Bob-omb to the ground three times to defeat him. Upon being defeated, Big Bob-omb is surprised that he was defeated by someone who seems weak, but acknowledges that his troops can stand to learn from Mario. After that, he explodes and releases a Power Star.

In Super Mario 64 DS, the battle is altered to work for Yoshi, since Yoshi cannot pick up enemies the same way Mario, Luigi, or Wario can, and Yoshi is the only available character at this time in the game. Big Bob-omb throws Bob-ombs at Yoshi, who must then grab one with his tongue and spit it at Big Bob-omb before it explodes. Big-Bob-omb's dialogue is dependent on the player's character: 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.
