Sand Crab

Sand Crabs, occasionally known as Land Crabs are large land-dwelling crabs with two legs and two huge pincers.

A Link to the Past
Sand Crabs first appeared in A Link to the Past where they roam near the rivers of Hyrule and Lake Hylia. They have a distinct movement pattern that makes them incredibly fast in a sideways motion, but slow when moving vertically. They are able to cause a surprising amount of damage with their claws; just two strikes to Link early in the game will kill him, so they must be treated with caution. They are thankfully defensively weak and can be defeated with a single sword blow.

Link's Awakening
In Link's Awakening, Sand Crabs live on the beaches of Toronbo Shores alongside Leevers. They are less powerful than they were in A Link to the Past, but can withstand more damage. In Oracle of Ages, Sand Crabs are found on Crescent Island, in the Southeast Corner of Labrynna. Like most enemies in the game, they are attracted to the Scent Seed. They typically appear in groups of two or more in narrow spaces on the beach, where there is not much room to navigate around them, causing Link to take damage if he tries to pass by them. In Oracle of Seasons, Sand Crabs are found on the Western Coast, near Horon Village.

Four Swords Adventures
In Four Swords Adventures, Sand Crabs sometimes appear in huge swarms on The Coast of Hyrule. In this game they do not move vertically, and simply move left and right at high speeds. If the four Links move cautiously, they can be destroyed easily with their blades and they can get a large combo.
