The video shows a cartoon dog with a brown body and a black nose, standing on a green towel on a sandy beach. The dog is holding a toothbrush in its mouth and is talking to a blue whale lying on the towel. The whale has white tusks and a pink mouth. The dog then jumps on the whale's back and starts brushing its teeth. The whale opens its mouth and closes it while the dog brushes its teeth. The dog then jumps off the whale and walks away. The video then shows the dog walking towards a cactus and a mermaid with red hair and a green tail, who is sitting on the towel reading a book. The dog picks up the cactus and walks away.
