Sesame Street Singers was a toy produced by LewCo in 1988. This electronic toy featured colored piano-style buttons and character heads with movable mouths. Each button, when pushed, caused a corresponding character on the top of the toy to move its mouth and "sing" to the music. Characters present included Big Bird, Betty Lou, Cookie Monster, Count von Count, Grover, Bert, Ernie, and Oscar the Grouch.
