I beat the Castle boss. I beat it on my second or third try. I probably finished a greater percentage of this stage than the previous two. I earned banana medals for all but one character.

...Which also meant I earned enough banana medals to play Jetpack. I easily got the Rare coin.

I also got another banana fairy from the overworld, which was just enough to unlock the ability to refight bosses in the mystery section.
I LOOOOOOVE Flying Omelette!!
