Cardbocchi has vanished. The rest of the choir tries to find him so they can help with whatever he's going through. Tomorrow is the final day of the competition and the choir's last chance to show what they can do. Will they make it there together?
Singing is fun. I learned 
that from you, Cardbocchi.
الغناء مُسلٍّ، تعلّمت ذلك منك يا صندوتشي
Dank dir habe ich das Singen
liebgewonnen, Studiobox.
Cantar es divertido.
Tú me enseñaste eso, Cartoncito.
Cantar es divertido.
Tú me enseñaste eso, Cartoncito.
C’est toi qui m’as appris
à aimer le chant,
Sei stato tu a insegnarmi
che il canto è così divertente, Danbocchi!
Eu vi como é divertido cantar
graças a você, Papelão!
Петь очень весело. 
И я понял это лишь благодаря тебе.
