GOKAAAAI... SILVER!
Also, the Ice Palace boss, Kholdstare, had a melting “fade” effect for its ice shell in its initial form programmed into the game to indicate how close you were to destroying its ice shell, but due to a programming error the effect didn’t work in the SNES version and the ice shell just suddenly disappears, with no indication as to how close you are to destroying it. This behavior was properly restored in the GBA version.
