S50, E23: Zoe sets off at a running start for her ballet jump but she slips and breaks her arm. When Zoey returns from the doctor, she still wants to play but she can't find anything fun to do. Charlie, Rosita, and Elmo come up with the idea of changing the words to the song "If You're Happy and You Know It," so Zoe can be part of it too, even with a broken arm. (Guest: Misty Copeland).
