I was watching the leaked song from "One Bad Apple" when I noticed this in the background. I immediately went: "DOCTOR?! WHAT ARE YOU DOING WITH DERPY'S COUSIN!?" And thus the crack began. Goddamn it, Cloud Kicker.
For some reason, I can never draw Derpy being happy D8 I don't know why. She's one of my favorite characters... ._. Celestia's going to send me to the moon, isn't she?
