Barbie and the Magic of Pegasus
What they share
Both films are directed by Greg Richardson, and they both carry the cozy, playful mood tags, and they sit in Animation / Family territory. If that's the register that drew you to Barbie in the 12 Dancing Princesses, the second film will land in a comparable space — through a different lens.

What Barbie and the Magic of Pegasus is
Apparently princesses need horses with wings. Princess Annika escapes an evil wizard and explores Cloud Kingdom. It all gets a bit equine.
