OK this RP is based of a fairly new board game called Rattlebones, I hate the game but I find the theme creepy, weird and kinda perfect for a light RP. Despite being a horror theme it's more of a haha spooky or at most the miniseries of It. I put it under fandom because this is nakedly inspired by a board game.

Here's the gist: You're playing a parent, you're at Rattlebones's circus and your child has disappeared suddenly a creepy voice on the intercom comes on:

"Welcome, girls and boys. My name is Rattlebones, and you have been cordially invited to spend the day at my Fabulous Festival of Dice! Play games! Win prizes! Ride the train! I'll be wandering about the park, and if you're the first one to find me, you win! Won't that be delightful?"

You need to find your kid before your kid finds Rattlebones and hopefully find out what/who/why about Mr. Rattlebones. While this is a free RP it might be elevated to Casual if people really get into this.
