Mikka's Magical Surprise

Princess Mikka has a palace, a dress for every occasion and even her own waterslide. But there’s one thing she wants more than anything else: a pet.
So when her parents surprise her with her very own unicorn called Marshmallow, all her dreams come true. That is, until Marshmallow’s magical horn zaps everything in sight!
Can Mikka help Marshmallow manage her magic, or will the kingdom be covered in orange juice, floating sheep and dancing teapots forever?
