In the 80's Sesame Street debuted a series of segments called Alphaquest in which a girl searches through a hall full of doors until she finds the corresponding letter the Alphaquest will talk about. There was a bunch of the Alphaquest segments seen on Sesame Street and featured a fun theme song as well. An interesting fact to know is that Grover appears in the S Alphaquest segment as a surfer and it is great. Although I don't know which actress played the girl on Alphaquest segments she was really interesting in the role
