Tone of Ocean Shamisen (music)
From Starfy Wiki
Tone of Ocean Shamisen is a variation of Tone of Ocean - the main theme of The Legendary Starfy series. It can only be found in Densetsu no Starfy 4.
After beating the game once, if the player returns to Hidden Village of Koimaro a radio can be found in the boss battle with Geishachi. If Starfy or Starly use a Star Spin on it, it will play Tone of Ocean Shamisen. This causes Geishachi to play a bunch of notes, making it harder for Starfy or Starly to defeat her.
Tone of Ocean Shamisen can be unlocked in the Sea Jams by purchasing it from Manianko's Shop for 1500 Pearls after beating the game at least once.
