Richard Hunt
Jerry Nelson played Sweetums in “The Frog Prince,” but when the character started appearing in “The Muppet Show,” he was reworked by Richard Hunt, who gave him a new voice, and continued to portray the character until 1991. Hunt also played other famous muppets, including Scooter, Beaker, and one half of the grumpy heckler duo, Statler and Waldorf.
