ah. with the .ast part i meant having like say just charizard with muscle growth but a whole new pokemon that also does it, so you don't need to make charizard also have weight gain and so on which would take quite awhile.
So you could say have eevee for breast growth and something else like typhlosion for it as well. and something like charizard and grovyle for muscle growth and so on.
anyways, good luck with the game development and such, you have done well so far!
