Mustard Mountain is the fourth cardinal area of the Mirror World. This area is difficult to reach, so it's likely not the fourth area visited by Kirby. Many of the Mirror Doors leading to Mustard Mountain are in obscure locales, since parts of the entire area are not connected and has to be reached using mirrors in other areas, mainly Rainbow Route. The mountain area may be named for mustard as a reference to the overwhelmingly yellow color scheme of the area; the base and underground areas are visibly different. Mustard Mountain is mostly a yellowish orange colored rock surface, and characterized by pools of lava, pillars of fire, and cascading lava-falls. All of the fire hazards damage any Kirby that comes in contact with it, cause a Copy Ability to transform into a wayward star, and can destroy Stars upon contact. Some of the open pits drop Kirby into an area of Rainbow Route, which increases the difficulty of traversing Mustard Mountain.
The boss of Mustard Mountain is Kracko, who guards one of the eight mirror shards. It is unknown if this Kracko is the same as the one in Dream Land, or a different Kracko.

Mustard Mountain is a very isolated area in the Mirror World, and its layout consists almost solely of one-way paths, which will start to feel like the layout of a more traditional Kirby adventure. Traveling through Mustard Mountain is difficult, and Kirby will find himself repeatedly accessing the various entrance tunnels from Rainbow Route to re-enter this area. Overall, there are 19 normal rooms, one hub, one Chest room (containing the map) and two Goal rooms.
The only way into Mustard Mountain is by means of Rainbow Route to the south. However, there is a Warp Star that will take Kirby and his chromatic companions to Candy Constellation from this area.
Mustard Mountain has two Goal rooms. Completing these rooms takes Kirby and his clones to the Goal Game, then returns them to the Central Circle of Rainbow Route.
