How about some spooky Pokémon tf tgs to a group of people at a costume party

the scariest thing Vino can write about is Anime girls

Witch needs a new familiar. She chooses you. (cat tf)

You and your friend agree to pick out each other's costumes, planning to embarrass each other with outrageous choices. Unfortunately, the costume he got for you isn't just embarrassing, it's cursed. (costume-becomes-real tf, probably tg as well)

You're done trick-or-treating and are sorting your haul. Say, that's a candy bar you've never heard of. Wonder what it tastes like. You eat it, and start feeling funny. (candy tf, plus vore when your sister comes into the room afterwards)
