... I mean putting them into their mouth like candy, with hair, clothes & Everything!... - Have you ever had a hair in your mouth?... - I can still remember how my own single hair accidentally got into my mouth a few times. That was disgusting! - & I couldn't stop coughing till I managed to get it out - so I was really surprised to see King Gristle putting Creek into his mouth just as he was: with a bunch of long Troll hair & his clothes on!... - Would a Bergen be able to digest it all? ( sorry, my 'practical mind' just spoke ). 

Btw when the scene where King Gristle was about to eat Creek but said something like 'Maybe we should wait for Trollstice' & then trying again convinced by Chef was repeated a few times & the other Trolls locked in the cage were looking at it & shaking like leaves out of fear - I found it 'one of the most stressful moments in the whole movie'. I watched that scene & said 'They're scaring Kids!' ( because the youngest viewers might have been scared watching it for the first time. & when I first saw it I was thinking 'No!' everytime he tried ).
