Would be great to add a new type to some of those normal pokemons, maybe add Psychic for Jiggly, Cleffairy family, like be a Normal/Psychic, only problem will be they will be weak to 2 type instead of only one, bug and dark weakness, resist to psy immune to ghost rest would be neutral. Too bad that you can't add new types yet, since jiggly could be Normal/Sound instead. Maybe we will find a way to add types with a script like we were able to add all pokemons to Firered. If you want you could try to add fakemon, some pokemons would need an evo to be stronger.
