Spiked Beetle

Spiked Beetles are recurring enemies in The Legend of Zelda series. They are hard, spiky shell creatures that must be knocked on their backs to be defeated. This can easily be achieved with Link's Shield. They roam around in random patterns, but once they spot Link they spin violently towards him, hoping to catch him with their spiky shell. They are first introduced in Link's Awakening on Koholint Island.

The Legend of Zelda: Oracle of Ages and Oracle of Seasons
In the Oracle games, Spiked Beetles can be defeated by using Shield to flip them over, revealing their weak underside and allowing Link to slash them with his Sword. They can also be flipped by using the Gale Seeds and repeating the sword attack.

The Legend of Zelda: The Minish Cap
In The Minish Cap the same shield and sword technique can be applied, however Link also has to option of flipping Spiked Beetles with the Cane of Pacci. In this game, the Spiked Beetle also gets more detailed characteristics, such as a bright blue shell and a small hole in the shell where a head might be hiding.
