Volcano Lu'ithreach is the final area of Island Saoire. As the title suggests, it is a volcanic world covered in jagged mountains, brimstone ruins, and oceans of lava. To get to the last world, Mario must enter the cave at the other end of Sandy Teampaill by crossing a bridge with Spindles. The level is also the home of the final boss, Dorcha Wiggler, which requires 35 stars to enter, making this star requirement the only requirement in the game (besides the the two MIPPS spawns). This level also contains the only other optional mini boss, the Whomp King.
