Sesame Street - 29x32 - Episode 870- Followmy.tv

Maria welcomes the viewer, when Prairie Dawn pushes her piano to the shop. She is sad because her piano no longer makes beautiful music, but funny sounds. Maria inspects, then asks if Prairie went to the park today. She recalls doing so, leaving her piano alone while she rested under a tree. Maria shows her that a squirrel stored nuts inside while she wasn't looking and caused the piano to sound that way. The piano sounds fine now and Prairie decides to share her happiness with Maria by singing a song for her (albeit slowly and off-key).
