Backstage appearances by Jim Henson characters other than Kermit

Kermit the Frog was the main character on The Muppet Show, and because of this, most of the backstage scenes prominently featured Kermit. Because Jim Henson was usually performing Kermit in the backstage scenes, his other characters were not seen backstage as often. However, his other characters still made quite a few appearances backstage. Here is a list of other Jim Henson characters who have appeared backstage:

Note: This list only applies to the main backstage area, and not other non-stage parts of the Muppet theater, like The Canteen and the dressing rooms. An asterisk (*) means that the character did not speak when he appeared backstage.
