Mayuge no Uta

A dog with unusually large eyebrows heads to the beach for a summer vacation. He runs across the warm sand, splashes in the gentle waves, and discovers seashells along the shore. The dog meets a friendly crab, a seagull, and a turtle, each offering a new experience. He tries to build a sandcastle but the waves wash it away, and he chases a beach ball that rolls into the water. As the sun climbs higher, he rests under a beach umbrella and watches the ocean sparkle.

Later, the dog encounters a lost puppy crying near the rocks. He helps guide the puppy back to its owner, passing through a crowded boardwalk and a small fishing pier. The two dogs share a snack and play fetch until the evening. When the sun sets, the dog sits alone on the sand, feeling both tired and happy. He realizes that even a simple day can be full of surprises and that helping others makes the adventure even better. The stars come out as he curls up on a towel, ready to dream of another day at the beach.
