I remember hearing some of the Muppeteers voice some cartoon characters. In some of the Sesame Street cartoons..... There was a cartoon called Flossie and Splat. And it sounded like Kevin Clash did the voice of the short purple monster called Splat. And in the cartoon, find the animals on the monkey's jungle T-shirt, it sounded like Kevin was doing an elephant. In the cartoon, Tall Tall Texan, I could hear Jerry Nelson voicing the Short Short Texan. Also in the cartoon, Lucky 13, Jerry was doing the singing western rat. And Baby Bear's cartoon, Hero Guy, that character was also voiced by David Rudman. Jim Martin also lent his voice in a few SS cartoons. Like a chalk drawing bird in 12 birds and a movie director in a 12 cartoon. And a few cartoon characters in The Puzzle Place. Victor Yerrid who is not only a puppeteer, he also seems to do voices for shows like Robot Chicken and Drawn Together. In Monsters Inc. Frank Oz did the voice of Fungus, the red monster with glasses and lots of eyes. Sheep in the Big City had a lot of Sesame Street Muppeteers doing voices. Stephanie D'Abruzzo, Joey Mazzarino, Fran Brill, and one time, Jerry Nelson.
