Spin Boarder is a Transformation that both Kirby and Prince Fluff can take on in the game Kirby's Epic Yarn and Kirby's Extra Epic Yarn. The two can transform into this form by getting the relevant Metamortex. Its first appearance is in the level Rainbow Falls, then it later appears in Mt. Slide and Meta Melon Isle.
Kirby wears a helmet with a yellow buckle. If Prince Fluff is the boarder, he gets one with an orange buckle. The one who did not touch the Metamortex grows smaller and hovers behind the other's head.
While in this form, Kirby and Prince Fluff enter a (mostly downhill) perpetual slide. The player can jump by pressing button 2, and can jump off an enemy by pressing button 1 while over it. By grabbing a Metamortex power-up, Kirby or the Prince gains wings which give further reach and height for the next jump. If a second player is present, they can shake the Wii Remote to make the boarder hover for a short moment every once in a while.
