So I was messing around with Hayley color schemes and the concept of Vylette being able to posess people and got this crazy idea. She was originally a goth shortstack slime but now she's a little more rave girl-y and I think I love it. Especially because I just had the craziest idea:

Bioluminescent slime girl rave.

I will be pursuing this.
