@NatureMC @futurebird @elduvelle Come to think of it, it's sort of odd that the popular names for them in Nordic countries (in Swedish it's "dammråtta" / dust rat) aren't based on the nisse/tomte (the former is the Danish and Norwegian word, the latter the Swedish). There's a *very* rich folklore about little creatures that live in the usually-unseen places of human homes and who are responsible for things like socks and small change "disappearing" ... which sort of sounds like what you'd expect an animist dust bunny to do.
The classic nisse/tomte can usually work minor feats of magic (like turning invisible whenever someone is looking at them!). In modern Scandinavia they're often associated with Christmas, and they sometimes have part of the role that Santa Claus does in the Anglosphere (eg. parents will tell small children that smaller presents are from the nisse who lives in the attic - and who you can get on friendly terms with by leaving him a small bowl of rice porridge).
(Stories about them can actually be traced back to Pre-Christian Norse mythology!).
