Flint Queen

The Flint Queen serves as the boss of the cave Flint Palace and doesn't directly harm the player's Pikmin. Instead, it summons Doodlebugs to poison them. To defeat the Flint Queen, simply throw Rock Pikmin to break it's shell. Once its shell it broken, the Flint Queen will become extremely agitated and summon even more Doodlebugs. Use Purple Pikmin to finish it off.
