The Earthquake Glitch refers to a glitch performed by Kirby using his down special move, Stone. The glitch will cause the shock waves from Stone to spread out over and over very rapidly. The glitch is performed on sloped surfaces, but not all such slopes can be used for the glitch. In Stage Builder stages, the glitch can only be activated on the edge of a right-facing slope. It is possible to use Stone on the slope, slide to the edge, and then activate the glitch. The glitch does not eliminate the time limit for using Stone, so it cannot be continued infinitely. However, the player can simply initiate it again.
