You happened to be in a mansion where some of the things looked like snake things. Wandering along the corridor of the mansion, they heard a snake hissing and decided to check what it was. When you reached the door and slowly opened it, you saw Snake Fruit Cookie who was coming up with a plan and wagging the tip of a snake's tail and laughing with a snake hiss

-"Hehehehe ssss... hmm?"

They looked up when they saw you

-"Sss.... Who are you?"
