The Song Sewer is a treasure in Hey! Pikmin. It is a silver harmonica with small decorations near its edges. It is roughly five times the width of Captain Olimar, but is only about one-fourth his height. It can be found very early in the game, as it's the third treasure of the first area, First Expedition.
Collecting the treasure
Near the end of the area, the player will encounter the Song Sewer, placed above Olimar on a twig. The player just has to throw 10 Pikmin onto it, and then follow them in order to retrieve the treasure a bit further ahead.

“The tunnels in this device convert air currents into musical vibrations. Isn't that the dullest description of an instrument you've ever heard? Blame the S.S. Dolphin II. I'd rather call it... a sculptor of wind.”
