Octorok

Octoroks are common, recurring enemies in The Legend of Zelda: Breath of the Wild and the entire Legend of Zelda series. They are octopus-like creatures that appear in many variants and usually attack by shooting rocks at Link through their mouths.

In-game
There are five variants of Octoroks, and one more type added in Master Mode of the DLC. Octoroks hide underground if Link gets too close.

Rock Octoroks
This is a common and standard variant of the enemy that appears mostly in hot or fiery places, such as Death Mountain, but also some cold places, as well as the Gerudo Desert. They spit rocks, as their name implies, and can be killed by placing a bomb in its path before it sucks in air and detonating it once it is swallowed. If Link places a Rusty object in its path, it will spit it out as either a Traveler (50% chance), Soldier's (35% chance), Knight's (10% chance), or Royal (5% chance) quality. This Octorok disguises itself as a rock on the ground.

Forest Octoroks
This Octorok disguises itself as some leaves or shrubbery and spits out rocks. To defeat them, Link can perform a Perfect Guard with his shield, bouncing a rock back and destroying the Octorok. If its shrubbery is cut down, it comes out of the ground, confused, leaving it vulnerable for attack.

Snow Octoroks
These Octoroks are diguised as a snowy patch of grass and spits snowballs at Link when he comes in its range. Similarly to the Forest Octoroks, performing a Perfect Dodge deflects their snowballs back at them to kill them. If their shrubbery is chopped down, they pop, surprised, out of the ground, leaving them vulnerable for attack.

Water Octoroks
These Octoroks disguise themselves as a water plant. They are commonly found in bodies of water, such as lakes and the oceanside, and they spit rocks at Link. Just like the Forest and Snow versions, deflecting the rocks with a Perfect Guard can kill them, as well as shooting them with an arrow, and if their shrub is cut down, they will come out of the water, confused, leaving them open for attack. While raining, they inflate and hover above the water. Using bombs or Urbosa's Fury is effective, too.

Treasure Octoroks
This Octorok, which appears in sandy and snowy places, disguises itself as a treasure chest. The chests aren't magnetic, and Magnesis is not effective against it. When a bomb is detonated near it, it pops out of the ground, confused and vulnerable for attack. These spit rocks that can be deflected with a Shield or Perfect Guard, and once killed, drop many Rupees.

Sky Octoroks
This unique, Master Mode-exclusive Octorok does not attack Link, but holds planks with Enemies or treasure chests on them. They float in the air near water and Sheikah Towers, usually in groups of three or four, and come down when a Bokoblin Horn sounds, or when Link whistles. They can be killed with one Arrow, and when killed, drop their planks and their contents.
