(Bonus Entry, don't vote) An embellished interpretation of the Castle theme from Super Mario Bros.

Intentionally heavy on the bass and drums. I also went with a lot of marimba to give it some organic flavor.

Went a little more organic with the percussion and added some choirs and percussive toys, but there was no getting rid of the bass (both guitar and synth).

Not much deviation from the original but I changed the B section around so the melodic line is being traded between my two lead synths. I also added some whoosh effects throughout to simulate the feeling of an actual race.
