Master's Instrument

The Master's Instrument is a treasure in. In the US and European versions, it is a pink "Mario Paints" pastel stick labeled "Peach Pink", which is a reference to the Super Nintendo game Mario Paint and the character Princess Peach. In the Japanese version, it is a different brand of pink pastel stick. It is found on the first sublevel of Glutton's Kitchen.

Collecting the treasure
The Master's Instrument is found in sublevel 1 of the Glutton's Kitchen. It is located inside a box with a Dwarf Bulbear in it, so the player must be careful when aiming their throws. There are also many more Dwarf Bulbears that can get in the way while carrying the treasure, so make sure the enemies are defeated as well.

Trivia

 * Despite having a changed design in the North American and European versions, the icon for the Master's Instrument is unchanged from the Japanese version in Pikmin 2's Nintendo GameCube and New Play Control! releases.
