"A huge bug that stretches from the ground to the sky. You can't defeat it unless you inflict damage to its head."

Geldarms (ゲルドアーム Gerudoarm?) are enemies from Zelda II: The Adventure of Link. They are slender, worm like creatures found exclusively in the deserts on the western continent. They are white in color and their only weak points are their heads. Their heads are normally held out of reach atop a long body, but an attack to the body causes Geldarms to burrow into the ground where their vulnerable heads are exposed. Link gains five experience points for defeating a Geldarm.
