I've been trying to get Sandy saying, "Oh, wow!" on video all week. I think I've finally got it - you'll want to turn your volume all the way up, though. She comes into the room and starts looking at the ornaments on the tree. Initially she is hidden by the tree, but as she comes around it, she says, "Oh, wow! Wow! Wow!"
Also, here is a short video of her wearing my shoes and clomping around with Sage.
