power trixie

My 3 year-old sister is a huge fan of the show, we actually watch it together. Even though she was just in one episode, The Great and Powerful Trixie is one of her absolute favorite ponies, however being that she's only 3, she can't say the full name so she just calls her power Trixie.
Therefore the title.
I've actually gotten used to just calling her power Trixie as well haha.
