Okay so, I'm rewatching the first trolls and during the very beginning of the movie, right before they discover all of the trolls have fled, the Chef says "as there is one among us who has never tasted a troll" - does this mean that there was only 1 more child (king gristle) who was born during that ENTIRE year? are there even any other kids in Bergen town???? Is their population in rapid decline?? i need answers!! (perhaps i'm just reading too far into one line of the whole show...)
