Octogon

A relative of an Octorok, this enemy is nearly identical to it's cousin save for it's color and size, being around three times as large. This enemy does not really attack, instead, it acts as an obstacle. Link had only one way to defeat this behemoth, knock it into a nearby pit with a couple of sword slashes. It is unexplained why this creature lacks the ability to spit rocks like it's relative, but the Octogon may explain the origin of the Big Octo, who ultimately took the Octogon's place in later games, such as Ocarina of Time, where it plays as a Mini-boss of the Dungeon:"Inside Jabu-Jabu's Belly."
