Well, Edd, Tom, Matt, and Tord got themselves stuck in Equestria. What more do I need to say? Oh yeah, the aliens, Eduardo, Zanta, the evil movie director, and Future Edd followed them.
Cartman, Kyle, Stan, Kenny, and Butters enter the world of Equestria, plotting against bronies who live in an all-brony community. But everything takes a major turn when they meet one brony in particular-who's different from the rest.
