Miles
From Muppet Wiki
Miles Robinson is the adopted son of Susan and Gordon on Sesame Street. Susan and Gordon's adoption of Miles in 1985 (beginning with Episode 2122) was a major event on the show. Subsequent episodes dealt with the infant Miles' adjustment to his new family, and he would gradually become one of the familiar kids on the street. Miles' birthday is December 4th.
In a dream sequence in episode 2313, Gordon and Susan imagine what Miles would be like as an adult (played by Kevin Clash in a cameo).
As a teenager, Miles would form his own band. In 2006's episode 4112, Miles graduated high school alongside Gabi, despite the fact that the characters' respective births on the show occurred four years apart. A flashback in this episode also revealed that Miles was shy on his first day of kindergarten.
Miles and Gabi now work as assistants to Alan at Hooper's Store.
