If you are fighting as either Goten or Trunks in a battle with the skill FUSION in their custom trays, here's something to laugh about. While fighting, do fusion (P,P,K,K,E). Then you will have to press a combination of buttons to perform the fusion dance. If you press them correctly in the right order, then the fusion will be succesful and Gotenks will be born. But if you want to have some fun with it, then do this. Perform the fusion technique (P,P,K,K,E). Then when you have to press the other combination of buttons, do them wrong. If you press the wrong buttons, then Gotenks will be really skinny and look funny. If you miss the last few buttons then Gotenks will be fat and tired and will not be able to use any moves.
