Oh! I have seen the Japanese cotton monster in other media; I did not know it had a name, and a background even. Yes, I see a potential inspiration behind Swirlix with it being able to float and be monster-like. I doubt it would evolve to physically resemble the ittan-momen, but if it did, it would ""fly through the air at night" and "attack humans, often by wrapping around their faces to smotherAHEM LICK them."
The ittan-momen could become Mega Chimecho's revenge.
Icing sugar and fairy/ice, that's creative! It looks to me like it will remain fairy, though... perhaps becoming a fluffy cloud-like animal of some sort. Fairy/flying is more plausible in this sense, actually.
I want Spritzee to become a lot like Xatu in stature, and fights with a cane. Its round body form is reminiscent of Natu after all... hahah someone on the design team really wanted a plague doctor reference in pokemon somehow, and has a good sense of humor.
Amaura's evo is HU-- relatively large in respect to a lot of pokemon

Ugh the fossils are so great, every time I see them I must pause to admire. I don't know who I will choose!
Fire/water on Clauncher would be fine, as long as it doesn't turn into a boiling engine or something.
"You are the fungus to my Paras." Nope, I've never listened to her stuff before. Currently browsing some of her work for anything familiar....... BLUE JEANS. Yes, I've heard this song on the radio.
