Spiked Beetle

Spiked Beetles are a type of beetle first encountered up on Koholint Island in Link's Awakening. In normal conditions, without enemies, a Spiked Beetle will crawl around a room at a leisurely pace. When an intruder is spotted, they will spin towards an adversary in hopes of stabbing them to death with their razor sharp carapace. With leverage, an object such as a shield can be used to flip them over, exposing their weak under-belly. Since their first appearance, Spiked Beetles have also been spotted in Oracle of Ages, Oracle of Seasons, and The Minish Cap.

Quote from The Legend of Zelda: The Minish Cap's Spiked Beetle figurine: "Appears in dungeons. Covered in hard, spiny shells. Few attacks work on them. You have to flip them over to hurt them."

Strategy
A shield helps greatly against Spiked Beetles, as it is the only item capable of revealing their weak underbelly. However, in the Oracle Series, Link is also able to rid the monsters from his path by use of Gale Seeds.
