At first you didn't think anything of it. The park was abandoned after all, so it only seemed natural for it to have a few strange things.
You begin to walk down the dirt path, ignoring the doll to keep exploring. Perhaps there was something more interesting in this park. Either way, you knew you had to solve the mystery behind its closing.
After several minutes of walking, you stumble upon what appears to be an old carousel. Out of a random spike of curiosity, you decide to try and see if it still works. You make your way over to the control booth and give it a go, lightly pressing the green button.
To your surprise, the dusty thing begins turning, slowly at first, but gradually speeding up. Amazed, you stand there and watch the carousel for a minute. It wasn't until you thought about turning it back off that something caught your eye.
You squint to try and make out the figure, only to realize that it was the doll from earlier, sitting on a white horse.
sorry if this wasn't any good, I've never really role played before...
