Sims 4 Ocean Exploration expansion pack [Aquariums, scuba diving and houseboats]

Underwater Diving areas

There are underwater diving areas that Sims can explore and that are interactive and actually visible to the player. Players can find treasure chests, explore underwater caves or sunken shipwrecks, harvest seaweed and catch fish swimming around. The fish that have been caught can be brought to the surface and exhibited in an aquarium.

There is a scuba diving skill. The higher the skill level, the longer a Sim can stay underwater and the less depressurizing time a Sim has.

Aquarium

There is an aquarium in town that you can stock with fish and other marine life like colorful sea slugs. These can be caught while scuba diving. There are giant aquarium tanks that you can stock with fish. There is an aquarium tunnel object that Sims can walk through, and it can be stocked with fish as well. Aquariums are a new type of community venue. There are saltwater tanks (with corals and rocks) and freshwater tanks (with kelp and wood branches) 

Houseboat

Houseboats are a new type of home that Sims can live in. Houseboats are editable in Build Mode like a regular lot, except you can't add a basement.

Whale watching

There are whales jumping out of the ocean that you can go watch with your houseboat. You can offer paid whale watching tours or diving tours with your houseboat by clicking on the tourist information center.
