They disguise themselves as stones, sometimes surprising the player. When immobile, they are invulnerable to attack, though they can be hit with a pickaxe to knock them back, making them mobile again.
To identify the Rock Crab, look out for rocks with shadows smaller than usual, sometimes slightly overlapping nearby rocks, as well as rocks on dirt patches (not including Nodes). Hitting a Rock Crab with a weapon rather than a pickaxe will result in a hit sound and a 0 to appear, letting you know that it is an enemy and not just a rock.
The Rock Crab can only be dealt damage if it is mobile, and not hiding beneath its shell. Strike an immobile Rock Crab with a pickaxe to make it mobile again.
Striking a Rock Crab with a pickaxe enough times will knock the shell off of its back, and will cause it to flee. Alternatively, setting off a bomb near a Rock Crab can remove its shell, and will cause it to flee as well.
- 1.0: Introduced.
- 1.4: Fixed bug that caused striking an unshelled crab with a pickaxe to produce the same sounds and debris as hitting a rock.
