 * Unicorns are possibly the fastest creatures in The Sims series so far, because of their incredibly fast running ability that most pets don't have.
 * The Sims may have a lifetime wish The Fairy Tale Finder which requires only to Adopt a unicorn
 * Unicorns can be found easily at night by going onto the Map screen, and looking for an Arora Borealis floating above a lot.
 * Unicorns can be bred to horses and the offspring has a chance of being a unicorn as well. The offspring of unicorns are usually born with either one or both horse traits fairly advanced regardless of if they are unicorns or not.
