Guma

Guma is the Japanese name for an otherwise unnamed enemy from The Adventure of Link. These foes somewhat resemble giant, humanoid moles, and constantly hurl balls-and-chains in an upward arc, making approaching them somewhat difficult.

Trivia

 * Interestingly, this enemy's name can also be transcribed as Gooma, which is the name given by the translation team to a new boss exclusive to non-Japanese versions.
 * The Doomknocker is an enemy in the same game which has attacks that are similar to that of Guma. Its Japanese name (ヘルグーマ) translates as "Hell Guma."
 * The Guma's fighting style is also very similar to that of the Hammer Bros. from the Super Mario Bros. games, in that it occasionally stops throwing for a brief moment, leaps into the air, then continues throwing.
