Uni is excited to go to her first magical unicorn sleepover. At first it is fun even though Uni isn't good at any of the games the unicorns play, but then she begins to feel sad. However, when dark falls and the other unicorns get scared, Uni helps them build a tent to feel safe together and tells them a story to put them to sleep. Uni is finally happy that she has found something she's good at.
