Troll House v NotorosThe troll fan-named Troll House or HausTroll:
This meanie was lurking inside a house in Denmark, snatching the odd bit of wildlife and trying to ensnare Emil as well.
Dusklings (fan-named Notoros):
This was a colony of very similar trolls that developed a crust to protect themselves from the sun, but they also had the (unique?) ability to speak more-or-less intelligibly.
