So just saw this last night and first off all I can say is AWESOME! While it takes a few liberties with the movie it's a truly amazing display of costuming, animatronics and puppetry.
Now on to the Vore
Now there's not much, but there's a scene with shadows puppets where Viking and several other items are swallowed by large Dragons. Though the best of it is during dragon training where they talk about wrestling young dragons and several Actors wearing costumes showing them wrestling young Gronkles are rolling around. One of them has the gronkle on it's feet with a pair of legs kicking and flailing out of it's mouth.
So yeah, great show. Good time had by those of all ages, and a little Vore tossed in if you knew where to look.
