Cloudsdale Cheer Ponies

Spring Step and Lilac Sky are two female Pegasus ponies who appear in Rainbow Falls as cheerleaders for the Equestria Games qualifying team representing Cloudsdale.

Spring Step appears again in the episode Equestria Games carrying the Cloudsdale team's flag during the Games' opening ceremonies.
