Hit the green flag multiple times. The animation sometimes works, and sometimes doesn't. I suggest watching in fullscreen. Fennekin (Easy): Just like your average Pokémon Chimchar, "Max" Knows some decent moves, but they aren't very strong since he is a rookie. Only @TheFireGuy360 and @cedpath can remix.
Egg moves are fair game for me, so don't say I'm cheating just because Chimchar doesn't naturally learn Focus Energy... Also, after hours (aka. minutes) of experimentation, I finally figured out a way to keep Max's neutral animation running without messing up the other costumes.
