The Vehemoth Phosbat is the Boss of the Distant Tundra in Pikmin 3, it is the first boss encountered but the second fought in the game. The Vehemoth Phosbat is a huge bioluminescent moth-like creature with a giant gaping mouth. Defeating it will free Captain Charlie who was swallowed by the beast at the beginning of the game and make the Heroine's Tear fall from the ceiling. The Phosbats are juvenile form of this creature.
The Vehemoth Phosbat is able to renders itself completely invisible in dark environements. When approaching the Capitains, it will render itself visible thanks to its bioluminescent hairs and start creating a powerful vortex with its mouth, if the Pikmin are trapped in the vortex, they will be eaten after a short amount of time. to defeat it, the Captains will have to use Yellow Pikmin to light up the room which will render it vulnerable to attacks. When attacked the Vehemoth Phosbat will release a cloud of toxic dust, the dust cannot kill Pikmin but it will scatter them around the room. Once two light bulbs are lighted up, the Vehemoth Phosbat will activate the Phosbat Pods in the room, those pod will continuously spawn Phosbats unless it is exposed to light. Once the big light bulb is activated, the Vehemoth Phosbat will be stuck in its "weak" phase and easily defeated.
