Luke, son of the musical instrument shop, found a flute which could automatically play music in his house. He won the championship in the school folk instrument competition with this flute, which made his friend Kachi jealous. Kachi stole Luke¡¯s flute and played it by the sea. But what came out of the flute played by Kachi was nasty noise, which even killed animals in the nearby farm. Though Kachi knew nothing about this, his behaviors caught the attention of the Giant Saver team and Seaman. The Giant Saver investigated the case from the farm, tracking the sound and found Kachi. Seaman reached the spot at the same time. The two parties fought against each other. Consequently, the Giant Saver rescued Kachi and Seaman snatched away the flute with super elf.
