This is music that plays during battles with Chocobos, as requested by GiggityNinja. The music was recreated with Mario Paint Composer.
Yes, it's finally happened. I found a use for the baby noise. In this case, a baby chocobo. It was the closest thing I could find to approximate a chirping sound.
If you're interested in other classic Final Fantasy music (pre-PS2), I plan on recreating a lot more, so please feel free to subscribe to my videos. Also, if you have any specific FF requests, I'd be happy to add them to my list, assuming I can find sheet music and an audio file for the song, so that I can fill in the missing gaps in the sheet music.
