Wario Land 4/Sapphire Passage

Sapphire Passage is one of the harder passages in the game. It's not quite the hardest, but yet it's not the easiest. It's best to say that it resides in the middle of the six passages.

Levels

 * Crescent Moon Village
 * Arabian Night
 * Fiery Cavern
 * Hotel Horror
 * Catbat

The Boss of the Sapphire Passage is Catbat.
