Booming Cavern

Booming Cavern is a cave that is in Pikmin: Invasion of the Giants. It has five sub-levels, and the final boss is the Giga Volatile Armored Cannon Beetle. It has the hazards of fire and explosions.

Sub-levels
Sub-level one- This is, of course, the first level. It has a Decorated Cannon Beetle, and there is also a Fiery Dweevil and boulders will fall down in two places. It has the Time Warrior (actually a ninja figure), and the Useless Parchment.

Sub-level two- This is an only-explosion level, so leave all but the Orange Pikmin where they are, or in a safe little corner. There is a Volatile Dweevil, and also two sheargrubs. There is a little corner that has a Volatile Armored Cannon Beetle, and behind it is a LEGO brick that is called Building Cornerstone.

Sub-level three- This has absolutely no enemies whatsoever, except for a few Female Sheargrubs, and a bunch of butterflies. There is two Ivory Candypop Buds, and there is only one treasure, the Activus Sphere (actually a marble).

Sub-level four- This is the final floor. There is nothing here but a big arena, and if you walk into it, the Giga Volatile Armored Cannon Beetle will fall from above. Kill it, and it will release the Boom Guard, an upgrade that will make you immune to explosions.
