Prototype Detector

The Prototype Detector is a treasure in Pikmin 2. It is a toy called a "", produced by Nintendo in the 1970s. It is found on the last sublevel (5) of the Hole of Beasts, and is held by this cave's boss, the Empress Bulblax. Retrieving this treasure unlocks the Treasure Gauge as an upgrade. Like some other treasures, if the player defeats the Empress Bulblax, but does not have enough Pikmin to carry the Prototype Detector, which requires the strength of 35 Pikmin, it will change weight to match the player's army.
