Over The Garden Wall

I just found a video of Shannyn Sossamon singing with Elijah Wood in the upcoming animated mini series Over The Wall. Could anyone tell me who's her character? And when she will appear? I tried to look for it on this site but she's not even listed in the credits.

EDIT: Oh never mind, her character is young girl named Lorna and she's being forced by a witch to do housework day in and day out. She starts a friendship with Writ (Elijah Wood's character) and they later develop romantic feelings for each other. I should learn to use the "show more" tab more often.
