I've heard that at low percents (0-25ish%) Jigglypuff can rest Fox out of his upthrow -> upair since at that point it's not a guaranteed combo yet. Could someone elaborate more on how exactly that works? Is it just a matter of spamming down-b when you get thrown, or is there more to it like SDI-ing down or something? Also, are there other characters where something similar to this happens (I think I remember seeing it works on Captain Falcon too)?
