Unstrung Racket

The Unstrung Racket is a treasure in, that can be found in the Serene Stream area. It is a regular metal bottle-opener. The treasure is half the height of Captain Olimar, and two times his width.

Collecting the treasure
At the bottom of the first lake of the area, there are some dirt blocks. One of them hides a doorway and, on the other side, the player can encounter a Crested Mockiwi. Killing it will reward Olimar with the treasure.
