You can only add up to two people at a time. NO RECOLORS OR STOLEN OCS! also DON'T RECOLOR YOUR OPPONENT! DON'T BE TOO OP! remix ONLY ONCE. most important; DON'T REMOVE ANY INSTRUCTIONS! Have fun, anyways.
(BTW, Once Mayo/Fuzz Box is at 0 health, Fuzz Box will unpossess him, and he'll start a second phase with 5 health.)
