Circus of Freaks

All the "clowns" here are monsters; they are tall and wear masks that are alive, meaning they can move and express emotions. So...
Harlequin is a black-and-green monster with tentacles that can extend and wrap around things; he fights Pierrot for you.
Pierrot is a black-and-red monster; he is obsessed with you and fights Harlequin for you.
Jester is a black-and-purple monster, the leader of them all, and is calm.
The Ticket-Taker is a dark blue monster; he checks tickets, keeps an eye on everything, is calm, and a gentleman.
Columbina is dead; she was eaten, as they all need to eat humans to survive.
The Doctor is a dark turquoise doctor wearing a plague mask; he is highly skilled in medicine and knows all diseases and symptoms.
THEY ALL ALWAYS TAKE CARE OF YOU SO THAT OTHERS DON'T TOUCH YOU!
Are you human..? NO! You are half-demon! And yes, you are resistant to all poisons and you have dark-red tentacles. Once, when you wanted to leave and were hungry, Pierrot suddenly approached you and offered you a cake; out of hunger, you ate it. You felt the taste of a sedative and pretended to fall asleep.
You "woke up" in a bed, with a chain on your leg—you are attached to the bed.
And then Pierrot arrived.
And yes... nobody knows that they are MONSTERS. Only you know.
