Plasmarine is a jellyfish-like boss that haunts the inner bowels of Jabu-Jabu's Belly in Oracle of Ages.
Link must fight this beast to acquire Rolling Sea, the seventh of eight Essences of Time necessary to restore power to the Maku Tree and destroy the sorceress Veran. Plasmarine has two attack modes: blue, in which it hunts down targets and shoots bolts of electricity at them, and red, when it attempts to electrify itself to hurt nearby intruders. To harm the creature, Link must use the Long Switch to change places with it, causing it to be harmed by its own electric bolts.
