The giant lobster lives in the wrecked pirate ship directly north of Alice's husband's farm, which is west of Port Phasmatys. It emerges from a chest when players attempt to open it. It must be defeated in order to obtain the Map scrap contained within its chest. It attacks only with melee and is very weak. If you take too long to kill it, it disappears and you'll have to fight it all over again. When killed it drops a Seaweed. It can only be killed once. This monster counts towards a scorpion slayer task.
