Mega Tweeter

The Mega Tweeter is a special item in Pikmin 2. When you unlock it, your whistle is able to have its calling range increased. The visible circle on the screen becomes 150% larger in diameter. This makes it easier to call a group of Pikmin that is scattered everywhere, or when trying to use it in conjunction with the Pluckaphone. In order to get this ability, you need to get the Amplified Amplifier.
