Ovejita is a Spanish-speaking lamb who appears in the Murray Has a Little Lamb segments with Murray Monster on Sesame Street. She assists Murray by giving him 3 clues for what kind of school they are going to that day. She gives the clues in Spanish. After Murray repeats each word and asks what it means, she reveals what it is in an unexpected way, such as having the item fall from a tree or appear in a pizza box. When he finally guesses what kind of school they are going to visit, she repeats the type of school in Spanish.
At the schools, she participates in the activities with the children and with Murray. Although she rarely speaks during these segments, she can frequently be heard giggling happily.
