Loni Dunne is an overly-excitable entertainment correspondent in the online series, Statler & Waldorf: From the Balcony. She's a female, purple-skinned, blond-haired Whatnot Muppet.
In Episode 17, her first appearance, she discussed the 2005 Oscar nominations with her co-host, Ted Thomas, and literally exploded from her excitement over the nominations.
She returned in Episode 23, where she talked to the Tom Cruise Muppet, who jumped up and down uncontrollably and accidentally kicked her head off.
The puppet was used as Clarissa on Muppets Tonight, and she was used as Denise on the French series Muppets TV.
