Karen Leigh Prell (born July 26, 1959)[citation needed] is an American puppeteer and animator. She is the performer of Red Fraggle in Fraggle Rock.[1]

Early life and career

Prell was born on July 26, 1959, in Florida but grew up in Seattle, Washington.[citation needed] She also performed some characters in other Jim Henson films and has enjoyed a significant second career as a computer animator for such studios as Pixar and DNA. On Sesame Street, she performed Deena Monster, as well as several background and one-off characters. She performed on the show from 1980–1981 for seasons 11 and 12, then returned in 2019 for season 50. She also performed in the 2003 attraction Sesame Street 4-D Movie Magic. Her website includes notes about working with Jim Henson and pictures of her custom puppets.

She was an animator for Geri’s Game and also worked on animation of A Bug's Life and Toy Story 2.[2]

Prell also works as an animator with Valve.[3]

Outside of her works on shows, Prell has made public appearances performing Red Fraggle, like appearances at Comic Con. At Dragon Con 2013, Karen Prell was joined by fellow puppeteer Kathryn Mullen as part of the 30th Anniversary of Fraggle Rock where they performed their respective characters. She returned to perform Red Fraggle again for the 2020 Apple TV+ reboot Fraggle Rock: Rock On!, and the upcoming reboot of the series, of which she is also co-executive producer.

Personal life

Prell married fellow Muppet performer Mike Quinn. They lived for a decade in England before moving to California to work for Pixar. Since divorcing in 2004, Prell and Quinn have continued to work together on different projects, usually involving the Muppets.
