Girubokku

Girubokku is the Japanese name for an otherwise unnamed floating eye enemy from The Adventure of Link.

These enemies greatly resemble Moas in being giant floating eyeballs; however they do not appear to be ghosts, and they fight rather differently, traveling around the screen for a short distance before opening their single great eye, which is Link's only opening to attack. They gradually close in on Link and attempt to surround him, closing their eyes to render themselves invincible. Another difference is that Girubokku are always visible, whereas some Moas usually require the Cross to be visible.

Due to their similar appearances, Girubokku may somehow be related to the Patra or Digdogger.

Trivia

 * Their name evokes the Japanese term which is onomatopoeia meaning to stare at something, and possibly, meaning to gaze vacantly.
