love song

Exploration Stage: House on the Reef
From: Isabelle
Description: Want to know what Insu and Inhyo's new voice needs? The celestial sea is huge, so we need to make sure our voices reach every nook and cranny of it. So...I get it! We can use my recordings of whale songs. Can you find it for me?
Completed: This whale record contains the voice of the whale, the giant of the sea, at its full volume. Don't listen to it unless you really need to. It will damage your ears. But if you listen to the whale's loud voice, you can hear it in every corner of the ocean.
