Octomine

Octomines are recurring enemies that appear in and. It is an exotic form of the Octorok that can only be found underwater. They are so named because they are an explosive species that detonate on impact, and closely resemble naval mines.

In, Octomines are encountered while Link operates the Salvage Arm to find Treasure Chests underwater. Two kinds of Octomines can be found: a sleeping type that remains stationary and an active kind that propels itself through the water using its snout, either upwards or from left to right and vice versa. The crane must be maneuvered between the Octomines as it travels down the depths; if Link fails to take caution and avoid them, they will explode and the crane will eventually sustain excessive damage and be rendered inoperable until he has it repaired at the Shipyard.

In, Octomines can be found beneath the sea at the Ocean Floor in the Ocean Realm. In this game, only the upward-moving variety appear. They pose no threat to Link or his Train as they are unable to make contact. Similar to the floating Barrels seen above the water's surface, the hero can destroy nearby Octomines by shooting them with the Cannon. Destroyed Octomines yield Rupees and Train-repairing green Hearts.
