Glittering Cannon Beetle

The Glittering Cannon Beetle is a species of Lithopod, and boss found within Pikmin Z. The species resembles its Larva stage, and it never truly leaves its underground tunnels like such, but it's body is covered in glistening, emerald green armor plating. The armor's only on the front though, as the rear is bare and hidden underground for most of the fight.

Biology
The Glittering Cannon Beetle is an underdeveloped Lithopod that remained life underground. Like other Lithopods in its family, the Glittering Cannon Beetle is capable of shooting projectiles at its enemies. During the fight, it is able to shoot typical boulders, fire rocks that can burn Pikmin, and Bomb rocks that explode after a few seconds. It is unclear as to how it can do this.
 * diet: roots, tubers
 * predators: ???

Piklopedia Entry
''A rather imposing beast on the surface, the Glittering Cannon Beetle mainly eats tubers and roots, and is vulnerable if it's pulled out of its burrow, or loses its armor. It is highly territorial, and drives intruders away with many a aimed projectile, so best to keep your distance if you can.''

Strategy
At first in the fight, it can't be hurt due to its strong, and durable armor, unable for your Pikmin to attack it directly. You'll have to avoid much of its projectiles and keep your Pikmin from getting hurt. Red Pikmin are encouraged for this fight, since they can't be burned by Fire Rocks. Once it starts to shoot Bomb rocks, make sure to grab whatever Bomb rocks you can before they explode. Once you do that, wait for it to inhale for an attack, and have it suck one of your bombrocks, able to damage it and break its armor. Repeat this process until its armor is blown completely off.

Once the armor is destroyed, the battle mode changes. It will begin to burrow around underground, and poke its head out of the ground at random points of the boss arena, continuing to shoot its projectiles at you. You're able to throw your Pikmin onto it now that its armor's gone, but it will shake them off quickly and reburrow. Repeat until the beast falls defeated.
