A really really old trick that's been known for a while. But I figure since it hasn't been posted up yet, i'll put it up. If A Snake player is recovering low with his up B, grab him on the way up. Mash the Z-button till he lets go, and he'll fall to his death. This also works on Sonic. If he's recovering low with his spring, grab him on the way up/down and let him go off of the edge. He'll fall to his death as well. The way that it works is that a grab release does not count as a hit, not letting the opponent do their upB recovery again. Therefore, when you release them, they don't have any other way to recover.
