The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necesary, capitalization should be fixed. For more information, see the new capitalization policy.
The Cobalian Octomoth serves as the second boss in Ratchet & Clank: All 4 One. It is encountered in the Aldaros Plains, sent by Commander Spog to defeat the heroes. This is a guide to defeat the monster.
The Cobalian Octomouth is an easy boss. The Octomoth's attacks are by stabbing the heroes from below with its tentacles. To damage the Octomoth, the gang must first attack the boss' tentacles, preferably with melee and throw attacks to save ammo. Once all the tentacles have been attacked, the Octomoth will be stunned, allowing the gang to fire at its open mouth. Repeat this strategy to defeat the Octomoth. Beware though, as the battle rages on, pieces of the arena will be destroyed, making it harder to move.
