Octogon

In Oracle of Ages, it acts as the Boss of the Mermaid's Cave. It is unexplained why this creature lacks the ability to spit rocks like it's relatives, the Octoroks. It bears a resemblance to Big Octo, who appears in Ocarina of Time, where it plays as a Mini-boss of the Dungeon:"Inside Jabu-Jabu's Belly." Big-Octo can also be found in Majora's Mask in the southren Swamp.
