If you give a hat proper conditions… it’ll evolve into an AJ. Good to know.

I like 3’s outfit and 5’s look.

Seems Derpy saw her unevolved form:

All of them including the hat.

Number 5’s top just screams very likely wardobe malfunction

I actually like 3 more than I should. Just give her 2’s kerchief and weird little bootie things and that’d be awesome!
 
Also WE HAVE BECOME HAT

#3 please. Or maybe a #3½ is that a thing we can have?

Ah, crap, she bacame an accesory!

She devolved into a mere hat.
