So every now and then, in addition to the multitude of other jobs she has, Rainbow Dash helps Miss Cheerilee teach her Gym Class to the young foals of Ponyville as well as coach the official Peewee soccer team, this is one of those sessions with Rainbow Dash and Cheerilee playing the parts of teachers and referees for the game.
 
Rainbow has a hard time being a fair and impartial judge given her adorable adopted little sister’s team with her friends are one of the best, but with Cheerilee helping, what could go wrong? For those wondering, yes Rarity did make those outfits.
