What happens

No Simpsons regulars appear; this cartoon scene shows a large grey shark swimming over a blue seabed dotted with orange coral-like growths and purple rocks, while two divers in black wetsuits, blue fins and purple tanks swim above it. A third diver follows behind the shark, then the shark swims on past green seaweed, and it turns to bite into a clump of green kelp, its jaws open with red gums and sharp teeth, then chews on the leaves. Later the shark is seen head-on among drifting seaweed fronds with bubbles rising. The scene ends on a wide blue sea under purple hills, where a dark green leaf-shaped creature with a head and bubbles rising from it swims through the water.
