I couldn't even find the obvious hiding spot this time so I'm really glad you posted the sneak preview of where ratti was this time round as I would never have seen that XD
I think pretty much all lullabies are creepy regardless of where they come from x_x people in the past were definitely a hell of a lot tougher than we were if they could go to sleep to that, although I guess it's different when you're too young to put much meaning to the words and the melody is nice XD
There is anothe spot, but as the video has earthy tones and Tuula is agouti (brownish) it's quite a challenge, so there's another spot but here is one of the two moments.
Well the story harbours a lot of legend in Iceland and is a well known part of their folklore. Some native told me that the mother was in fact in love with the father but abandoned the child due to the possible shame... there are a few variants... but what is really clear is that Iceland has a very rich folklore both about elves (Hudafolk) and Ghosts that in fact have many different categories. I think many children songs are creepy, I don't know if you have watched my take on Ring around the Rosie, for me that ones is the creepiest hahah :) and still naively sung by children in their games. But this one more than horror is eerie and sad and full of moody melancholia
