"On a Sour Note" is the twenty-first episode of Viva Piñata's first season.
The Piñatas start a rock band after being tired of not doing anything and become a success after a Sour joins the band as lead singer. The sour is hyperactive and hard to restrain. However, when he becomes a regular Profitamole, Pierce loses his memory and forgets his lines to play at a concert. Franklin Fizzlybear takes over as lead voice.
