Sensei Gray

Sensei Gray is a color which only Sensei is able to wear. It is also a bait item, and obtaining it results a ban.

Trivia

 * In the October 2010 What's New Blog post about the Halloween Penguin Style catalog, there was a gray penguin outside the Night Club, but this "gray penguin" is just the adornment of his coat, not "the real color".
 * In the Animals We're Helping Catalog there is a gray penguin, however it has a different shade.
 * The penguin on the EPF Badge Pin wears this color.
 * It is the only unavailable color which has a color value, because Sensei wears it.
 * In the Club Penguin Times, Sensei said he's the only gray penguin because he's old.
