Oscar the Grouch as he appears in stage shows and theme parks including Sesame Street Live and Sesame Place. There are two variations of the character: the puppet/costume hybrid and the full-bodied walk-around. The former is operated from inside a large trash can that serves as his body (when entering and leaving the scene, Oscar walks while inside the can, his legs worn by the puppeteer). This puppet, bigger than the actual Oscar, is intended to not look small compared to the other Sesame Street walk-around characters, but very often this is the case. The full-bodied walk-around debuted in 2012. In stage shows, Oscar is performed to a vocal track by Caroll Spinney (or in the case of international appearances, the person who dubs Oscar's voice in that country).

Like all the other Sesame Street walk-around characters, Oscar was originally designed and fabricated by the Muppet Workshop, who eventually handed these duties over to VEE Corporation.
