My Little Pony: The Movie
From My Little Wiki
In this big-screen debut of My Little Pony, the Little Ponies must stop the evil witch Hydia and her two incompetent daughters Reeka and Draggle from covering Dream Valley in a purple goo called "the Smooze". The Little Ponies find help from the friendly Grundles and the magic powers of the Flutter Ponies. But will that be enough to save Ponyland?
