Sapphire Passage

The Sapphire Passage is one of the six passages in the Game Boy Advance game Wario Land 4.It's a large, labyrinth of a pyramid which Wario must make his way through to defeat the Golden Diva and rescue the Princess Shokora. This passage is horror-themed, with several ghost-like enemies such as Skeleton Bird, Men'ono and Yūrei. The boss of this passage is Catbat, a ghostly combination of a cat and a bat. The Jewel Pieces in this passage are sapphires, and the CDs are blue. This is considered the most difficult main passage. Other passages include the Entry Passage, Emerald Passage, Ruby Passage, Topaz Passage and the Golden Pyramid.
