Glunk is an enemy that appears in main Kirby series games, first appearing in the series's first game, Kirby's Dream Land. It resembles a sea anemone with a green or yellow body and pink or red, sometimes vaguely hair-like tentacles on top of its head. Its face consists solely of two big, round eyes with black pupils.
Although Glunks usually reside in water, they can be found outside of it as well, making them one of the few amphibian enemies in the series. Their only strategy of self defense is regularly blowing bubble-like projectiles upwards or — in Kirby's Dream Land — towards one side. They do not yield any Copy Abilities in any of their appearances.
