Fire Mountain
Fire Mountain is located at F3. It has a Secret Cave, a platform, a Big Octo, and sunken treasure.
Secret Cave
The secret cave can only be accessed by shooting the volcano's lava plume with an Ice Arrow. The game will set a five minute timer in which the player will have to finish the cave before time runs out. The player will have to scale the mountain and enter the cave inside where they will have to jump across hardened lava platforms and defeat the Magtails on the other side. Once they have been defeated, a chest will spawn that has the Power Bracelets in the vanilla game.
The player may skip the lava platforms by jumping onto the center wall and using the Deku Leaf the rest of the way.
Platform
The platform in this quadrant has two chests: a Sphere 0 chest that is readily available and one that will spawn after destroying all of the canons. These chests have a Golden Feather and Yellow Rupee (10) in the vanilla game.
Big Octo
The Big Octo has eight eyes and will give the player an Orange Rupee (100) in the vanilla game.
Sunken Treasure
The treasure can be located by opening Treasure Chart 37 when charts are not randomized which has a Silver Rupee (200) in the vanilla game.
