I personally would love to see a Derpy centered cartoon as she is one of my favorit minor characters. What do you think would happen in an episode like that?
Derpy CENTERED?! AWWWYEAHAWESOME!!! Anyway, I think that it would be kinda like an interview, with Derpy listing the best ways to eat a muffin, favourite muffin flavors, wierd muffins around the world, etc.
