The video shows an animated dog character wearing a yellow and black uniform and a black cap. The dog is sitting in a purple submarine with yellow accents and round windows. The submarine is floating on the surface of a calm blue ocean. In the background, there is a clear blue sky with a few white clouds. The dog is seen looking around and smiling. Another character, a boy with brown hair, appears in the later frames, swimming in the water next to the submarine. The boy is wearing a red and white striped shirt and green shorts.
