Song Sewer

The Song Sewer is a treasure in. It is a silver 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.

Trivia

 * The French name for this treasure translates to "wind sculptor", which sounds very similar to the name Olimar suggests in the English log, "sculptor of the wind".
