Guma

Guma is the Japanese name for an otherwise unnamed enemy from Zelda II: The Adventure of Link.

These foes somewhat resemble giant, humanoid moles, and constantly hurl ball'n chains in an upward arc, making approaching them somewhat difficult.

Trivia
Interestingly, this enemy's name translates as Gooma, which is the name given by the translation team to the boss known as Jaiantu (Giant) in Japanese.
