Since you mentioned Grinch I've got to tell you about the dream I had: Stiles lives in Christmas Town and feels like he doesn't "fit" with the other elves, he tries tho. At a festival conference he meets Derek, the werewolf from Halloween Town, and everything about Halloween fascinates Stiles, he visits Halloween more and more and ofc he and Derek fall in love. In the end it's revealed that Stiles isn't an elf, he's a grinch. So he decides to move to Halloween and live with Derek.
Oh my God this is like a crossover between How the Grinch Stole Christmas and The Nightmare Before Christmas (but like, a reverse Nightmare Before Christmas?) and I have to tell you, anon, I am INTO IT. I love the idea of Stiles learning about Halloween and falling in love with both the holiday and with Derek, and finally finding a place where he feels like he belongs.
And I have to make sure everyone has read this fic where Derek is a Grinch and Stiles is a snow elf (which is slightly different than what you’re talking about but equally adorable, and if you haven’t read it YOU SHOULD): Jingle Grouch by aggybird.
