[on where she studied animation] Can't answer that one, I didn't!

I thought about what I wanted to see in a cartoon-I'm drawn to the macabre, odd stuff, like my taxidermy. I'm very crafty, always making things, which lends itself to a witch character. And tone-wise, I wanted to keep it real, even have nuggets of education. Like in "The Summoning," I tucked in a great factoid about poo consumption in the animal kingdom.

I still can't believe I have a project with Frederator. It was my childhood dream to make a cartoon, and I'm a huge fan of Pendleton Ward and Natasha Allegri. I even got to work with Natasha, who directed "The Summoning"! I was fangirling, it was so hard to act cool.
