Always be yourself. Unless you can be a unicorn . . .

When she's abandoned just before Christmas, Peggy the pug puppy is taken in by a foster family with a unicorn-mad little girl named Chloe. Her older brother, Finn, doesn't little dogs. And Chloe wants a unicorn for Christmas, not a puppy. Believing that anything is possible, Peggy decides that she will somehow turn into a unicorn to make her new friends happy. All she needs is a long silky mane, a glowing horn, and the ability to do magic! Easy-peasy, right?

But all of Peggy's attempts to turn into a unicorn go hilariously wrong. From knocking over the Christmas tree to getting lost in the snow and accidentally stealing the show at the nativity play, Peggy remains a pug. How will she ever find a forever home if she can't change who she is?
