Sensei

Sensei, formerly known as ??????, is a penguin that appeared when the Dojo got damaged by lightning, returning from "a long journey". He used to be seen at the Dojo Exterior, but now he can be found inside the Dojo, sitting on the cushion next to the variable-colour pot. He has the color Gray, which is not currently available to players and appears to be a very old Penguin. He has a small white beard (Possibly he is related to Rockhopper), thick white eyebrows, and a conical straw hat. He was seen digging out the Dojo. He later revealed he would launch a card game for training Ninjas, known as "Card Jitsu". His name was revealed to be "Sensei" a Japanese word for 'teacher', implying he is the ninja trainer. Apparently, he said that came over from far away to return, which means he has been to Club Penguin before. He presently is handing out Starter Cards in the Dojo to players training to become ninjas. He awards penguins colored belts for their progress in the Card Jitsu. Also, once players get a black belt, Sensei can be challenged and if one wins, they become a true Ninja. Sensei will always pick the opposite card of what you pick, unless you are a black belt, that is. He almost always speaks Haiku.

Interview
In the Penguin Times Issue #163, the Club Penguin Times interviewed Sensei and he revealed some things about Ninjas and himself.

A Possible Relative
Rockhopper could be a possible relative of Sensei, seeing as they both are the only penguins to sport beards and bushy eyebrows. They both seem to have a knack for exploring, as well. This has not yet been proven.
