This is the Courtyard. It was covered in snow for many moons! Enter the Dojo and take the path of the Ninja.
The Dojo Courtyard is the entrance to both the Dojo and the Ninja Hideout. The door to the Ninja Hideout is behind the stone tablet with Japanese writing written on it. You can enter the wooden door if you move your cursor. It is accessible by the Map or the EPF Spy Phone.
The Dojo Exterior was first covered with snow for many years. After the Halloween Party 2008, part of the Dojo was struck by lightning, producing a hole in the top left corner which you would either walk up to or click to enter the Dojo Exterior. The name of this covered-up snow was discovered when the room is loading it said the Dojo Exterior. But when you would click 'Find' on someones player card on your buddy list, it would say Dojo Roof. The Dojo Exterior had a mysterious gray-colored Penguin digging up snow. His name was "The Sensei", however officially now known as Sensei, which means "master" in Japanese and is possibly used in kung-fu and other Japanese martial arts.
