To add to the whole pixie/monster au thing.
For harpies, dragons, and werewolves nesting is a BIG thing. So is gift giving. So a common courtship ritual is giving someone a piece of clothing or a blanket for while they nest. Which is typically done during ruts, heats, or child raising.
But pixies nest year round regardless.
So once pixie (temp name while i figure one out) is out and open about what she isโฆ. Well her nesting instincts go in full force. She is stealing and swiping stuff to add to her nest.
They cant figure out where their stuff is going at first.
That is until one of them looks in the bathroom sink cabinet. They find her stash of stuff and instantly recognize it as a nest.
After that they leave stuff out for her to steal for her nest. Recognizing that the pixie instincts is to steal the nest material.
(She has also absolutely stolen a few of ghostโs masks too. Its prime bedding material. And yes her behaviors are based off of squirrels some.)
