Cephalorock

The Cephalopod is a boss enemy first appearing in the game Pikmin:The After Years. It is a giant octopus-like creature that has four tentacles, a "helmet", and spits boulders. The Cephalorock has blue skin and disturbing red eyes.

Attacks
When entering into its lair, it will pop out of the ground and immediately start spitting boulders at you! The boulders move really fast so you have to watch out with your Pikmin. He will also start moving around after he has taken some damage. After half his health is depleted, it will start to throw Bomb-rocks. He can have up to four Bomb-rocks at once! Even though he is likely the 6th boss you will meet, he is really tough. This beast is located on sub-level 6 of Grassy Gulch and on a random sub-level in Rememberance Ravine.

How to Kill
The only way to hurt the Cephalorock is to trip him. You can only trip it by pulling its tentacles while he is stunned. To stun him, throw a Pikmin at him while he is sucking in air to shoot rocks, similar to the Armored Cannon Beetle battle. He will then become dizzy, so now is the chance to pull him. Use 10 Pikmin or 1 Purple Pikmin on each of his tentacles and they will automatically start pulling them. Once knocked down, he will be defenseless so you could start chucking Pikmin onto his back. Repeat this process a couple of times and watch out for bomb-rocks and you should defeat him in no time.
