Sesame English

[1] Launched in 1999, with Taiwan and China as the debut markets, the series differs from the typical international versions of Sesame Street in that it was devised as a supplement to ESL (English as a Second Language) instruction.

[1] Dr. Lewis Bernstein, producer and key developer of the series, explained that "The aim is to introduce English phrases and vocabulary in an entertaining way, using conversational language along with repetition, rhythm and rhyme, cool music styles, and lots of humor—much the way we do on Sesame Street."

[5] DVD releases of the series, available in the U.S., include five available audio languages for Tingo's dialogue: Spanish, Hmong, Korean, Mandarin Chinese, and Vietnamese.

Tingo, the only new Muppet character (operated and voiced by John Tartaglia), is a green, purple, and orange monster and an exchange student living in America with his best friend, Niki (played by Kelly Karbacz).

Teenaged Niki lives in the basement of her parents' home, and has an extended circle of family and friends, including grandparents, siblings Katie and Kevin, baby Jake, and the members of her band.
