The attic of the Muppet Theater is seen in several Playhouse Video compilations: |Muppet Moments, Muppet Treasures, Fozzie's Muppet Scrapbook and The Muppet Revue. Kermit the Frog and Fozzie Bear appear in the framing sequences of those videos, cleaning out the attic and reminiscing about memorable acts from The Muppet Show. Various props or characters often serve to trigger their memories of a particular song or sketch.
The attic is located above the stage, and can be accessed by the backstage left stairs up and through a door. (In Fozzie's Muppet Scrapbook, Kermit asks Fozzie if he wants to go paint scenery, and then goes downstairs to the stage.)
