Sensei

Sensei is an old penguin and has mastered all of the elements. He has a white beard, thick white eyebrows, traditional Japanese straw hat and a walking stick. Sensei refers new ninjas or students as 'grasshoppers.' He is a master of Card-Jitsu, and is also a teacher of it. He has a childhood best-friend named Tusk (a walrus), who has now become his bitter rival. Sensei uses a broken tusk from this rival as his walking stick.

Sensei can be found inside the Dojo, sitting on the cushion next to the variable-color pot, and also in the Fire Dojo and Water Dojo. He wears the color gray, which is currently not available to players.

Appearance
Sensei is the oldest penguin on the island, and the only grey penguin. He is one of two penguins to have natural facial hair, the other being Rockhopper. He wears a traditional conical hat and carries a stick.
