Hello. I know some Sesame Street Muppets that first appeared on any street segments, songs and years on each episode. Mine were Big Bird first appeared on the premiere episode where he tries to look at Sally, Oscar's first appearance which he was orange and talks to Sally, Bert and Ernie appeared on their own skits before Sesame Street, Kermit first appeared on the street where he sees Bob making the "W" in a dollar before he starts the "W" lecture, Cookie Monster first appeared on the sketch where Kermit tries to perform the "W" lecture, Guy Smiley and Sherlock Hemlock first appeared in 1970, Mr. Snuffleuphagus first appeared in the 1971 premiere, Sam the Robot first appeared in the 1972 premiere, Barkley the Dog on episode #1186, and of course, the Anything Muppets: the purple little girl, the pointy green head boy, the purple woman, the tall orange man and a Fat Blue-like man on the premiere episode.
