A modern day fantasy story where all these weird off the wall monster repellant things work not because they’re set in stone things but just because people believe really hard in them. But like it’s not a widely known thing– old wives tale things work for general things because the monsters belive themselves repelled by them some of the time, but others no. Then there’s the MC who is deadset that like, dandelions scare the crap out of vampires because they universally hate yellow. Why? Because it looks like the sun, so she decided when she was 3. Werewolves can be passified by a dog whistle. You don’t have to blow it– they’ll see it and not bother you because they know if you blow it it’ll hurt their ears and call their mom on them. Decided age 4. Or, if you don’t have a dog whistle, just make a dog hand gesture like a shadow puppet and they’ll run away because they’ll worry you’re going to fight them with it. Decided, also age 4. Boogymen are deathly allergic to lavender. Goblins are afraid of smiley stickers. Ghouls can’t make it past a vigilant stuffed animal. Nothing evil can survive a cat.
Nothing of this is technically sound, but because she so doggedly believes it all that nothing knows what to do with it. Make her make friends with a girl from an old school monster hunting family that insists everything she says is bunk and meanwhile she’s like “idk Sarah you should have some celery if we’re trying to find Vampires, it keeps their teeth clean but they’re more likely to talk to you if you eat it because they figure you’re friendly.” “Heather, what” “Well, that’s how i befriended Tim and he seems ok. Why are we looking for vampires again?” “Tim’s a vampire?” “Yeah, you didn’t know?” “He was outside in the sun!” “Oh, no one believes that.”
Basically i’m just amused by the idea of a girl throwing shit off and befriending monsters by being weird. Because weird is good.
