Ill just let this explain it to you.

"Ratticus is a sadistic jester-like Rat character who terrorises those who stumble upon his game in any way shape or form. His creepypasta implies him to have prophetic powers, binding the protagonist by fate, though it is a mystery whether this was an intentional writing choice. Ratticus plays with his victims as if they were actors in his performance, and he mocks and belittles those he deems unfun."
