The big boss battles at the end of each world in Yoshi's Island meant a change of pace, a walk away from the usually cheerful and calm songs. So this song proposes "Let's Get Serious", although my friend tends to say "cereal" instead of "serious"...so the title is an homage to him.

While the song's focus is mainly the Big Boss battle (and pays quite a tribute to it by staying quite true to the original), the song also includes a bit of the Mid Boss battle and the final boss. I used lots of organs in this song, which fit quite well in my opinion. I hope you can agree!
