Multiple modes characters? Anyone know if there is a guide I can learn from?

[bren]

I wanna stick super buu and kid buu in fat buu and have them working out the same character. Anyone know where an information guide on achieving this is? I've looked around, I may have the wrong keywords.

Thanks

I think that thing u are planning is a bit difficult to happen because when your char is thrown the sprites will reverse to fat buu!!
