What happens

No regular Simpsons characters appear; this is an animated map-style title sequence with a blue globe-like grid, a yellow compass rose marked N, and a dashed white route line. Green cartoon sea serpents with striped purple-and-white tails appear at the top and then slide across the screen in the early frames, while the words RUSSIAN WATERS in white serif capitals sit on the blue background. As the sequence progresses the serpents pass out of view, the title drifts and shifts position across the screen, the dashed route curves and recedes, and the background fades from blue to dark purple and navy.
