Rosita is feeling homesick for her abuela and for Mexico. Seeing how much Rosita misses Mexico and her abuela, Big Bird and friends decide to bring Mexico to her by decorating Sesame Street to look just like Mexico! They also bring in authentic Mexican food and Luis sings a traditional Mexican song. Rosita is truly surprised and grateful when she realizes what everyone has done. To everyone’s surprise, Rosita’s abuela shows up too! She missed Rosita so much that she had to fly in to see her. Rosita couldn’t be happier! They all continue the fiesta together.
