Of course, I'm a HUGE fan of the new My Little Pony show. It's cleverly written, beautifully animated, and some of the songs are really great. It's such a good show, in fact, that its biggest fans are college-age males (and of course 20-30-female-somethings like me who grew up obsessed with MLP).

Of course, my favorite pony is Applejack, the down-home country girl with the can-do attitude. She's also a palomino, like Annie! Speaking of which, if you feel the compulsion to pony-ize your own equine, you can use General Zoi's Pony Creator and make all your dreams come true! This is Annie and Mr. Strut, My Little Pony style:
