for this achievement your going to need to do fathers synergy assist, which means u need fuzzy lumpkins. incase u dont know who that is your gonna be looking for a character thats fuzzy pink and shoots a meat transforming gun. now wat your gonna have to do is get lucky enough to get fuzzy lumpkins and when u do u need him to shoot your oppoent with his gun and turn them into meat and while they're transform into meat u have to k.o. them. this is easier to do when u have two controllers.
