Mysterious Wall

Mysterious Walls are walls that only appear in The Minish Cap. Their only purpose is to fuse Kinstones with, which causes another Goron (for the first time the first one just gets stronger) to come and help the other Gorons destroy a wall in a cave south of Lon Lon Ranch. If Link fuses Kinsones with all 6 Mysterious Walls, he will be able to fuse Kinstones with a Goron. Doing this will wake up Biggoron.
