The Keeper of the Stage is the Yellow Puffle that first appeared back in 2007 when the Stage was still under construction. It would appear randomly out of the scaffolding. When the Stage was completed, the Keeper of the Stage stayed there, and has a part in all of the plays that go on there. It can usually be seen if you press the yellow lever on the Switchbox 3000.
Back in 2007, a Yellow Puffle appeared at the Plaza when the Stage was under construction, as well as at the Forest during the Halloween Party 2007. It would appear randomly. When the stage was completed, if you moved your mouse over the two Puffles at the top, it would appear in the balcony. When the Switchbox 3000 was introduced, if you pressed the yellow lever, it would appear somewhere on the stage. It takes part in all the plays. On March 4, 2010, it temporarily disappeared along with Yarr and The Keeper of the Boiler Room.
Quest for the Golden Puffle: The golden Puffle statue retracts, replacing it with the keeper, who is asleep. The keeper wakes up, and goes red faced at the audience before being replaced by the golden Puffle statue.
Underwater Adventure: The treasure chest at the front of the stage opens, revealing the keeper asleep. The keeper awakes, winks at the audience, and slams the treasure chest.
Ruby and the Ruby: The keeper appears riding a train above the stage, strangely, he is bigger than a Penguin so he can appears better to the audience.
Squidzoid vs. Shadow Guy and Gamma Gal: The keeper jumps out from behind a building, dressed as a super hero with a black mask and a red cape. He then jumps past the buildings and exits the stage.
