OldCp.biz

OldCP.biz was a CPPS made my Tennis. It was closed, then Tennis opened SnailsChat, a game for 8-15 year olds. OldCP reopened as ClubPenguin.pro, then closed and reopened as OldCP again.

Another CPPS
OldCP isn't just another CPPS. It has custom commands. Instead of (Ex- !jr) you would use /jr. Tennis also made custom rooms for Tennis like Tennis or Tennis. You don't have to purchase stuff like Tennis, and they have custom items you can only get on Tennis.
