floor 1889:
An old man who says: "hi simonTHEsleepy, why do you constantly change names? You had that name before entering the Tower, 3 years and 2 days ago."
Then, the old man turns in to skeletron, and pushes you back to floor 1010011001 (do you know binary?)
Actually, why we didn't a party for the plantera achievement of the Tower?
