This mountain peak is the Snow Dojo.The time to master snow has come... Head across the bridge to battle snow minions. You are ready brave ninja!
The Snow Dojo is a room in Club Penguin, opened on May 23, 2013. It is where the game Card-Jitsu Snow is held, which can be played by waddling to the bridge on the right. It is found on a snowy cliff on a mountain that is accessed from a bridge from the Dojo.
Sketch art shows that Sensei was originally going to appear in the Snow Dojo, most likely meaning the bridge is the equivelant of Sensei's cushion.
The Snow Dojo mountain is actually the mountain where Sensei and Tusk battled. There is a giant rock covering a cave, which is where Tusk currently resides, after being covered in an avalanche from the mountains, and being trapped in that cave.
This dojo is different to the other Dojos, as there is no Legend or Instruction scroll, Sensei is not present at all, and there are no practice mats on the floor.
