Rita

From Muppet Wiki

Rita is the human hostess of "DragonTime," as seen in the Puppetman pilot. On air, she portrays the sweet medieval damsel Lady Rita. She sees herself as the star of the show (as the only performer who operates her own head), and often interjects unscripted musical numbers, to display her "talents" as a songstress. This occasionally frustrates the rest of the crew, and she and Del have a particularly antagonistic relationship. Rita is also having an affair with director Bud Stone.
