Super Smash Bros. Cheats

A cool Ness trick!
Ok. First of all, go to training mode. Your character has to be Ness and any character as a CPU. Choose an arena (I would prefer Sector Z) and go to a flat spot. Get 4 Red Shells and get far from them (not too far). Turn around and use PK Fire. If you hit them and have done it correctly and the shells look like just one shell, when you get hit, you're percentage should rise up to like 420%. Try it. Sometimes, some shells even disappear.
