Answered: Alternative universe disney miniseries

Ok so the plot starts off with the girl in the modern day and the prince from the extended universe which is a dog, He kind of jumps through a mirror to her world. The dog and her are chased by trolls from that other side of the mirror into the mirror that goes to the otherside of this universe along with her dad. She's actually snow white's grand child or some thing and her mother is the wicked witch. Could be placed in different hands idk!

It's a miniseries from TV late 90's maybe 2000's. Modern girl gets sucked into a fantasy world. The three trolls are always chasing after her and her father. They're sung a nice bluesy jazz song on the other side to fall asleep to on a island in a swamp in the first episode.
