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 Lava Crab, look for rocks without shadows, sometimes slightly overlapping nearby rocks, as well as rocks on dirt patches (not including Nodes).
The Lava Crab can only be dealt damage if it is mobile, and not hiding beneath its shell. Strike an immobile Lava Crab with a pickaxe to make it mobile again.
Striking a Lava 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 Lava Crab can remove its shell, and will cause it to flee as well.
