The Super Spring is a glitch that can be performed by Ganondorf in Super Smash Bros. Brawl. To perform the glitch, Ganondorf jumps on a Stage Builder spring and the moment he touches the spring, he uses the Wizard's Foot. If done correctly, Ganondorf will perform a strange flip-jump that takes him about two times higher than a normal spring jump.
This trick can also be done with Captain Falcon, but he will not gain any extra height. Instead, he will just perform the strange animation to a normal height.
