The path of the sound of water

Exploration Stage: Wonderful Cat Cafe
From: Detective
Description: Maybe the Creator's flute is on the riverbank. Legend has it that when the wind made music with a buzzing sound through the branches of a maple tree, the glacier melted and a river of warm water appeared, from which plants sprouted. There is something in the grass. Is this the creator's flute we're looking for?
Completed: Hmmm, it must be a flute, but it's not a finished product. This is the mouthpiece used to play the flute. I haven't heard anything from the spring girl about the features of the creator's flute, but this mouthpiece is decorated with a dragonfly ...... and the dragonfly has come to life and flown away! Let's follow it.
