For some reason I thought this one was called Frozen Christmas, and was going to say it'd have been better to call it Frozen Birthday.
Cause that's what it is. Elsa celebrating Anna in song and dance in whimsy, celebratory festive fashion with the cast y'allreadyknow.
It's a nice little short. Well-animated. Well-voiced. A not too particular but not bad, uplifting little Birthday trip with a red thread that's easy to follow. Literally.
rated 3.5/5: not bad at all
