The The Shrimpsons couch gag is the fourth couch gag of Season 29.
Based on "The Shrimpsons" opening sequence, the Simpson family (as fish) swim into their underwater living room, which is decorated with coral, underwater plants, and other decorations that are from the coral reef, and sit on the couch. Suddenly, a fishing hook grabs the couch with the family in tow, and is raised to the surface, where Ned Flanders grabs the couch and says, "Okily dokily!" as he places them inside a lobster cage. Once in it, Homer says, "Aw, our own home." However, a few lobsters are seen crawling towards the family.
