I think Marill is kind of representing a naiad- a water nymph; specifically of fresh water such as rivers, brooks etc.. Though it looks like a round mouse
it and Azumarill have traits of being heavily associated with freshwater- in terms of rivers etc. I believe. That would kind of make sense I suppose- when compared to other existing Water types.
Jigglypuff, well, I can't really argue against it
I it like a balloon/pudding spirit- which is quite Fairylike and odd I suppose- and it is partially associated with the moon (moon stone) but not as much as Clefairy.
Clefairy HAS to be retyped to pure Fairy! Anyone with me? Having it as normal/fairy would be odd because if anything warrants pure Fairy it is Clefairy and Clefable. Also, it would be nice for it to diverge away from Jigglypuff's line
I expect some of:
1st Gen: Clefairy and Clefable, Jigglypuff and Wigglytuff,
2nd Gen:
Misdreavus, Togetic, Bellossom, Marill and Azumarill (obviously
),
3rd Gen: Mawile,
Absol or an evo, Snorunt, Glailie, just Gardevoir in it's line, possibly Milotic, Skitty line,
perhaps a split evo for Shroomish
4th Gen:
Cherim, Pachirisu (give it something different), Togekiss, Manaphy,
Mismagius, Lake Trio
5th Gen: Audino,
Whimsicott.
Xerneas please be Fairy! Please!
