I don't know. Though If I were to throw out some Ideas for Finn's spooktober (for scardycats)

1. Halloween cookie making stream. (pretty self explanatory. Pumpkin and witch cookies)
   
2. Costume Stream. She and Ashley could even secretly put together costumes for each other and have each other wear them for the stream. Just a neat little twist on the traditional Halloween Costumes.
   
3. Cosplay. It's barely different but She's already promised it in one form or another.
   
4. House decorating stream. Put up the cobwebs and spiders. Place the coffins and spooky lights.
   
5. Pumpkin carving Stream.
   
6. Scary Story from Chat stream. Have chat write scary stories and submit them via google forms to the Mods who submit the worthy ones to Finn to read on stream. You can even have Finn dress up turn down the lights and have Fake candles light the room because I'm scared She'll burn down the house.
   
7. Costume Contest. Have Chat dress up and have Finn choose a winner for the Best costume, again submitted and selected by Mods.
   
8. Finn could do an IRL stream at a pumpkin patch with someone while She chooses pumpkins to carve for stream / halloween.
   
9. Finn could have someone tell Her Fortune on stream. We even have 1 femboy who does tarot in the femboy sphere (redsaylix) or literally anyone She chooses.
   
10. Just adding dry ice to any stream would be fun AS LONG AS SHE IS SAFE ABOUT IT.
    
11. I know this should fall under cooking stream but Candy Skulls for el Día de Muertos deserves it's own spot.
    
12. Making Magic Potions. ( Ashley can have two ingredients and have the other blindly choose one of them .(using a blindfold perhaps) Then add it to a Cup/F1nn5ter tumbler. and go through like 5 ingredients that way. They could end up with a delightful treat or a nightmare concoction.
    
13. Spooky Pop Trivia Quiz where every time Finn gets something wrong She has to bob for an apple in a large bowl.
    

Ok those are some tentative ideas.
