Fiery Cavern

Fiery Cavern is the third level of the Sapphire Passage in the Game Boy Advance game Wario Land 4. As its name suggests, it is infested with fire pits that spit out torrents of hot magma. Touching either will damage Wario. A unique enemy appears here, Iwao, that throws rolling rocks at Wario. Only a Ground Pound defeats them.

Upon hitting the Frog Switch at the mid-way point of the level, the whole area's lava, fire, etc, becomes freezed, and the Iwao become Yukiotoko. Some lava torrents freeze over, allowing Wario to use them as platforms to reach higher places. Wario will re-encounter areas that he has visited before hitting the Frog Switch, but all the heat has frozen over, so it seems like a completly different area.

The CD found in this level is called "You and Your Shoes", and once collected, it can be played in the Sound Room.
