The video shows a cartoon dog with a brown body, large white eyes, and a black nose. The dog is sitting on the sandy ground with a blue bucket next to him. He is using a green shovel to dig into a large orange sandcastle with a blue shell on top. As he digs, a small red crab with big white eyes pops out of the sand. The dog looks surprised and quickly covers his mouth with his paw. The crab then hides back into the sand, and the dog continues to dig.
