Lobstrosities are giant lobsters located in the southeast corner of the Underwater area of Fossil Island. Most weapons and shields cannot be equipped in this area. Weapons that can be equipped and used to kill lobstrosities include the trident of the seas/swamp and the brine sabre.

A fishbowl helmet cannot be worn in this area, but players can easily use the nearby air bubbles to replenish oxygen while fighting lobstrosities.
