The video shows a cartoon shark and dolphin swimming in the ocean. The shark is grey with a white underbelly and sharp teeth, while the dolphin is light grey with a pink nose. They are swimming near the ocean floor, which is covered in rocks, coral, and sea plants. The water is a clear blue-green color, and bubbles can be seen rising to the surface. The shark and dolphin are moving gracefully through the water, with the dolphin occasionally leaping out of the water.
