When the Horns, a family of Narwhalasi, come to Bark Story Land, Princess the miniature pony acts up."I think you're part of a family of monsters," she tells Starla, the first narwhalasus child to attend Bark Story Land Elementary. This hurts Starla's feelings, but when Princess' mother signs her daughter up for the new synchronized swimming team, coached by Starla's mom, the girls learn to get along.
