Unused Levels Edit

Fourth 2 Player Battle Level Edit
This Level is a Unused 2P Level, which is a Stage containing an arch of coins on-top of the arena, and also containing a unused block graphic that looks familiar into comparison to the SMB (Super Mario Brothers.) Garbage Block. This graphic has not been seen anywhere in the game apart from this stage.
