Sea Urchins are recurring enemies in the Legend of Zelda series. They are small, immobile, spike covered creatures that often block Link's path.
Sea Urchins make their first appearance in Link's Awakening, which features several enemies based on other Nintendo series. Sea Urchins look strikingly similar to the levitating enemies, Gordos, from the Kirby series, the main character of which also appears as an enemy in Link's Awakening.
Sea Urchins are found at The Coast, the first stage of Eastern Hyrule, the games second level. They are completely indestructible, acting as obstacles that damage Link. Walls of Sea Urchins will often appear at the edge of an area to block Link's path, and will disappear when Link completes a certain objective, such as defeating all the enemies in the area or pressing a Foot Switch.
