Holy ever-living Celestia. If you play the ocarina, you just hit the jackpot. Pony fan jessekruz, who shared an ocarina tab with us before, is back with lots more resources.
Check out all these songs you can learn on the ocarina: The Failure Song, This Day Aria, I've Got to Find a Way, Apples to the Core, So Many Wonders, B.B.B.F.F., Winter Wrap Up, Cupcakes, the Title Theme, Giggle at the Ghosty, The Perfect Stallion, and Babs Seed. Thanks so much, jessekruz!
