Sapphire Passage

The Sapphire Passage is one of the five passages Wario had to go through in the game Wario Land 4. This passage is ghost-themed, and contained the levels "Crescent Moon Village", "Arabian Night", "Fiery Cavern" and "Hotel Horror". The boss of the level is Catbat, a ghostly combination of a cat and a bat. This is one of the five passages.
