After Control Freak sends the Teen Titans to Pretty Pegasus World, Butterbean and Sparkleface were complaining that the unicorns were playing their music too loud. The Titans went to their house and fought them. Robin broke one of the unicorn's horns. The Unicorns said that they were playing their music to keep the Gumdrop Goblin away from their world. They couldn't play their music because Jelly Roll's horn was broken, but Butterbean said to play it from his hearts and the unicorns played the song.
- The unicorns can either be friends or brothers with one another.
