It's Song Day on Sesame Street! Nina, Rosita, and Lalo are practicing "Head, Shoulders, Knees, and Toes" in Spanish for their big performance. Mia wants to join but is hesitant because she's still learning how to speak Spanish. She loves speaking Spanish because it's something special about her family and decides to give it a try. When Mia gets frustrated, forgetting how to say the words in Spanish, Nina reminds her that she's special just the way she is, no matter how much or little Spanish she speaks. With help from Nina and Rosita, Mia keeps practicing and successfully performs "Heads, Shoulders, Knees, and Toes" in Spanish with her friends.
