From Zelda Legends Wiki
| Appearances: ALL zelda games(!) up till now.|
Habitat: Overworld, Dungeons
Attack Pattern: This varies a bit per game, but Octoroks are weak enemies that are encountered mostly on the overworld. Octoroks usually attack Link from a distance by shoots small rocks at him.
|| Appearance: Legend of Zelda|
Quick Facts: They come in two variaties; Orange and Blue. The blue ones are a bit stronger, but other than that there isn't anything particular different between the two versions.
|| Appearance: Adventures of Link|
|| Appearance: A Link to the Past|
Quick Facts: They appear in the eastern regions of Hyrule.
|| Appearance: Link's Awakening (DX)|
Quick Facts: In this game there is also an winged variant as well, which is a bit harder to defeat.
|| Appearance: Ocarina of Time/Majora's Mask|
Quick Facts: These Octoroks are different from the ones in the previous games, because they are stationary enemies that only shoot at you, when you are enough far away. Reflecting the projectile back with the Deku Shield or the Hylian Shield will kill the Octorok in one go. Oddly enough the Mirror Shield cannot reflect these projectiles.
|| Appearance: Oracle of Ages / Seasons|
Quick Facts: As with most regular enemies in the Oracle Series, it is just the Octorok from LA with a different color scheme.
|| Appearance: Four Swords|
Quick Facts: The sprite was polished up a bit, but other than that it still uses the same design as in LA.
|| Appearance: The Wind Waker|
Quick Facts: Two variants appear in this game.
|| Appearance: Four Swords Adventures|
|| Appearance: The Minish Cap|
Quick Facts: The well known Octorok also appears in TMC, and again its simple design was reused. It looks like the game creators reused the exact same FS sprite, but this time it is a bit lighter colored. In this game there is also a special Octorok called the Golden Octorok. The boss of the fourth dungeon in this game near Lake Hylia is also a bigger version of the regular Octorok and has even the same name.
This enemy is the true all-star among the creatures in the Legend of Zelda, for it is the only creature that appears in every single Zelda game so far, and that is pretty telling! These enemies are usually more a nuisance than a real treat for they usually only try to attack you from a distance.
Legend of Zelda
Adventures of Link
A Link to the Past
The Octoroks in A Link to the Past are like the others, but these fiends shoot the nuts everywhere when Link gets close!
Link's Awakening (DX)
Ocarina of Time
The Octoroks of Ocarina of Time look a bit sad, but they are total meanies. If Link is on a cliff or higher than the Octorok, it will jump up and Link can't hit it because it will fall down!
Oracle of Ages / Seasons
The Wind Waker
Four Swords Adventures
The Minish Cap
Manny's Art Casing
In TWW the sprite of the LoZ Octorok reappears on the object Manny is holding inside Carlov's Figurine Shop. This Octorok image even appears on the Manny's Figurine, when Carlov carves it out.
Super Smash Brothers: Melee
Because this enemy has appeared in all Zelda games so far it was given a trophy as well. The picture of the Octorok used there is based on the model from OoT/MM. The Octorok also appeared as a common enemy in the Underground Maze in the Adventure Mode of that game.
Super Smash Brothers: Melee
These common enemies made their debut in the very first Legend of Zelda game and have been a staple of every game in the series since. They shoot rocks from their mouths at high velocity, but the projectiles are simple to block and do very little damage. Octoroks have low stamina, so they don't pose much of a threat to good fighters.
