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 Smash Attack can defeat them. Upon hitting the switch at the mid-way point of the level, the whole area's lava, fire, etc, becomes frozen, and the Iwao become Yetis. Wario can use the frozen lava torrents as platforms to reach higher places. This level's CD is called You and Your Shoes, and once collected, it can be played in the Sound Room.

Time given in different modes
The time given to escape the level after hitting the switch varies between game modes.

Trivia

 * Given Fiery Cavern's placement in the Sapphire Passage and its theme, it seems to be based on Hell from Christian mythology. The way the level freezes over when Wario hits the switch is a possible reference to the term "Hell freezes over", denoting an unlikely event.
 * This is the only level in the Sapphire Passage where the Skeleton Bird and Minicula do not appear.
 * By zipping, it is possible for Wario to enter areas that he would normally only be able to access after pressing the switch. This allows him to collect treasures such as crystals, hearts, and the CD case twice: before pressing the switch and after it is pressed. )
