Armored Antenna Cannon Beetle

The Armored Antenna Cannon Beetle is an enemy appearing in Pikmin Galaxy Adventure. It, like the name suggests, is a bizarre combination of an Armored Cannon Beetle and an Antenna Beetle. The Armored Antenna Cannon Beetle is similar to the standard Armored Cannon Beetle in terms of health, defense, and appearance, but it is much slower and powerful and has a pair of antennae as well as a vulnerable grub-like backside. It can emit a noise similar to the one Antenna Beetles make, which attracts and pacifies Pikmin in its range. Its eyes also glow red instead of teal.

Olimar's notes

 * "A crossbreed of various species in the kettlebug and lithopod families creates an epic hybrid of the two families. It can suck in air particles and shoot a rock out of its snout. If something clogs the blowhole it uses to suck in air, the beetle's body temperature rises dramatically and it must cool off. It can also whistle, which attracts small creatures that are used to being whistled at such as Pikmin."

Louie's notes

 * "Edible, but it doesn't taste very good on its own. Season it with sea salt and other various toppings to add flavor to the meal."

Pikmin
The Armored Antenna Cannon Beetle's large fleshy abdomen can be attacked by any Pikmin type at any time, but the creature's ability to call Pikmin to its side can make targetting it difficult. It only utilizes this ability after shaking Pikmin off of itself, and with it, the creature has its followers stand in a line in front of it to crush them with its boulders. However, these Pikmin can be saved from their doom by throwing a Pikmin into the Armored Antenna Cannon Beetle as it inhales, which causes the creature to lose control of the affected Pikmin. Battling the creature with a healthy amount of Red Pikmin, Purple Pikmin, or Knight Pikmin is recommended for a fast and easy kill.

Spraying it with ultra-sour spray works but it can be time-consuming.
