I made a tiny Derpy plush too. This one's already reserved though.
I'll post pictures of it when the eyes and cutie mark will be done.
As always blaj blah blah Derpy, or Ditsy doo, is copyright to Hasbro. Pattern and plush and mine (Esme Toussaint 2012)
You know the drill, don't steal or claim as your own and such.
