The Keeper of the Stage is a puffle that inhabited the Stage, first appearing during the construction of the building. It would appear randomly out of the scaffolding. When the Stage was completed, the keeper stayed there, and since made a small appearance in every stage play, when the yellow level of the Switchbox 3000 was pressed.
Due to the permanent closure of the Stage, the Keeper of the Stage can not be seen anymore.
The Penguins that Time Forgot: It briefly appears behind leaves. Its expression changes every time it appears. First it appears as usual, then it leans to the side, then it sticks its tongue out, and then the cycle repeats.
Squidzoid vs. Shadow Guy and Gamma Gal: It jumps out from behind a building, wearing a black mask and a red cape. A signal of a puffle appears in the distance, and the puffle then turns around and flies away,
Team Blue's Rally Debut: It flies down from above, bounces, and falls in the basketball hoop. It then grins, and hops offstage.
