The Pony Tones are a singing ensemble of ponies who perform for various social events and charities in Ponyville. When first introduced, they are to perform for a fundraiser that Fluttershy organizes for the Ponyville Pet Center. However, prior to the fundraiser's scheduled time, Big McIntosh loses his voice during a turkey call competition. Using a potion that Zecora brews from poison joke leaves to deepen her voice, Fluttershy sings for Big Mac behind a curtain (suffering from stage fright) while Big Mac lip-syncs.
