An oyster hunter suit is a diving suit that can be built on the ground level of an Aquarium in a player-owned house with the Construction skill.

It is the lowest tier of buildable diving suits that can be worn in the underwater aquarium, where the default is a fishbowl helmet and diving apparatus. The oyster hunter suit allows players to open oysters in their Aquarium.
