The Hop Skip and Jump song is featured in the episode Dragonshy. Pinkie Pie sings it when Fluttershy is too nervous to jump over a gulf in their path. The music backing to the version of this song, as heard in the episode, was created by William Anderson to match the vocals that Andrea had already recorded.
A slightly longer version of the song completed the demo-recording stage but remained unincorporated into the first season of the show. It was later released by its composer Daniel Ingram on his SoundCloud account. It is very similar to the song above, though at a much slower tempo than the version in the episode. The final version of the song as heard in the episode was not produced by Daniel Ingram.
