What happens

Homer, Marge, Lisa, Bart, Maggie, and Grampa stand behind a curved brown railing and a woman with dark curly hair in a purple top, all looking down into a glass-walled undersea viewing tank filled with blue water, seaweed, and a pink sea creature. The tank is on a boat, and the scene shows the family and companions gazing at the sea life as the wall of water shifts and the fish and plants drift slowly past. Grampa, in a green shirt with white tufts of hair, turns and speaks in the final frames while Maggie in her blue bow and Marge in her tall blue beehive watch. Earlier, in the first frames, a small red-and-white boat with a cabin moves across a bright blue harbor past a lighthouse on a rocky island, with docked white motorboats and piers in the foreground.
