Mega Tweeter

The Amplified Amplifier gives you the Mega-Tweeter.

The Mega Tweeter is a special item in Pikmin 2 that it is part of the Exploration Kit. Unlocking it increases the range of the whistles of all Captains. The diameter of the visible circle on the screen increases to 150% of its original size, thus more than doubling the area the whistle affects. This makes it easier to call scattered Pikmin to your side. In order to get this ability, the player must collect the Amplified Amplifier, inside the Ranging Bloyster on the final sublevel of the Shower Room.
