Lowder

The Lowder is a beetle with a hard carapace that appears in The Adventure of Link and in the animated series.

The Adventure of Link
The Lowder is found in deserts and caves in Zelda II: The Adventure of Link. It generally moves slowly, but when Link is in direct sight, a Lowder will, much like a Rope in other games, streak straight at him with surprising speed. Link can easily defeat these foes with one strike from his sword, with the Downward Thrust technique being one of the most effective ways.

Animated series
A Lowder appears in the animated series; however, unlike its game counterpart, this Lowder is never seen attacking. Instead, it serves as Ganon's main transportation when traveling in the overworld since his teleportation powers are limited when not in the Underworld. Since the Lowder can climb walls, this allows Ganon to reach the tower where the Triforce of Wisdom is located, as seen in the "Cold Spells" episode of the series where the evil wizard obtains the Triforce thanks to the Lowder's abilities.

Trivia
Another Zelda II enemy, known only by its Japanese name, Aruroda, shares part of its name with the Japanese name for Lowder- Roda- suggesting some kind of link between the two.
