"Gravity Falls" Cast's Secret Message from D23

YH is at Disney's D23 Expo in Anaheim chatting with the creator and star of Disney's Channel's #1 animated series, "Gravity Falls", Alex Hirsch and his co-star Kristen Schaal! Alex tells us about the events that led to him getting the big call from Disney, instead of vice versa, plus he gives us a little impromptu taste of his characters Grunkle Stan and Soos! Also, see if you can decode our special secret message at the end! Hosted by Nikki Novak (@nikkinovak).
