Mia and Me is a super cute show that is currently playing in European countries.
According to their website:
Mia is a normal 12-year-old girl, living in a boarding school in Florence, Italy. But she owns a mysterious book and a magic bracelet that allow her into the wondrous world of Centopia, a realm full of Elves, Pans and Unicorns. Here she is transformed into a beautiful Elf with a unique skill: She is the only Elf in Centopia who can communicate with the Unicorns.
I’m looking forward to seeing more of these dolls and hoping they come to the United States!
