SeaWorld is a United States chain of marine mammal parks, oceanariums, and animal theme parks owned by SeaWorld Parks & Entertainment. The parks feature captive orca, sea lion, and dolphin shows and zoological displays featuring various other marine animals.

In "A Fish out of Water", Meg recalls a previous family trip to SeaWorld where Peter humiliated the family by punching out an orca, also known as a killer whale, that gives Lois a "kiss". Peter then demands to know how long Lois has had an affair with the whale.
