Phoebe and Her Unicorn

Originally a web-comic called Heavenly Nostrils. The story begins when 9-year-old Phoebe Howell, a girl in the fourth grade, skips a rock across a pond and accidentally hits a unicorn in the face. Freed from her own reflection, the unicorn – named Marigold Heavenly Nostrils – gives Phoebe one wish, which she decides to use by making the unicorn her best friend.
