The six and a half minute sketch stars Murray Monster and a purple lamb named Ovejita who only speaks Spanish. It features a Caribbean-esque theme song which is a rap variation on the classic nursery rhyme "Mary Had a Little Lamb", sung by Tony winner Lin-Manuel Miranda. Sometime during that season, the theme song was shortened. While the sketch appeared in every episode in Season 39, beginning in the following season, it alternated with Bert and Ernie's Great Adventures. Also during season 40, the guessing game portion of the segment is cut, and a shorter intro is added that leads them straight to the school.
During the segments, Ovejita tries to give hints to Murray as to what school they are going to visit and Murray always insists that the answer is on the tip of his tongue. The rest of the segment involves Murray asking questions and learning about what happens at the school, interacting with the children and teachers, and trying out the activities. Ovejita is seen participating as well.
The segments were directed by Joey Mazzarino and Matt Vogel (who directed the "Art School", "Soccer School", "Ice Skating School" and "Baseball School" segments). The segment's theme song was written by Judy Freudberg, Joey Mazzarino, Bill Sherman and Belinda Ward.
Though the segment stopped airing after Season 41, the format was incorporated into the tune in segments such as "Murray's Science Experiments" in Season 42 and "The People in Your Neighborhood" in season 43. In Season 44, the segment was brought back through the tune-in segments, featuring new school visitations and repurposed versions of archived editions. In Season 45, the segments began showcasing non-school locations.
