Computer appears regularly in "Elmo's World" segments on Sesame Street. One of Elmo's living crayon drawing furnishings, the computer bouncily attempts to present Elmo with his e-mail video messages with Elmo tending have to chase after it as it bounces around the room. Computer is accompanied by a mouse. Initially uttering a generic "You've got mail", Computer chants an energetic "Elmo has mail!" in later episodes, while a fluttering, winged mail icon appears on its screen. Computer's most active appearance was in the episode "Computers", where it was introduced and, it later replaced the "Elmocam" portion of the segment.
- The generic "You've got mail!" quote in early episodes may be a refrence to the AOL "You've Got Mail!" sound.
