This is the first in my line of Canon!Creepy Ponies - Scootaloo. Obviously she's an adult here, but luckily I positioned her legs so you can't see her (as yet unknown) Cutie Mark. I assume it will have something to do with being active - scootering, rollerblading, etc - so I based the image on that. She's all scraped and bruised from rolling around and now she's just chilling upside down against a wall, yup.
This is going to be one of the least creepy ones I post, so be warned. (I've got some terrifying things in store for Fluttershy, Sweetie Belle, and Applejack... among others.)
