huh, it's another one of those wierd quirks that is explained nowhere in the game. if you hold left/right during a darkslide and flickit you get the dark varial, but if you hold up/down you get the heelflip/kickflip in the direction of the grind.
I can't wait for VillainBandito to give this a 1
isn't a glitch. just do a heelflip catch out. i can do it with just about any grind now.
i still haven't figured out a way to reliably repeat this glitch
