Mega Amp
The Mega AMP is an enormous robot, the design of which is based upon a Kremling; the Mega AMP was constructed by King K. Rool and his Kremling Gang.
In DK: Jungle Climber, the Mega AMP appears as the boss of the third island, Ghost Island, in the Panic Factory; before King K. Rool has one of his Kritter henchmen, empowered by a Crystal Banana, enter the cockpit of the Mega AMP, he mentions that the robot was only partially finished being constructed.
In order to damage the Mega AMP, Donkey Kong, while avoiding energy balls and bombs shot by the Mega AMPs, would need to shatter a crytal in it's chest using a lever and unscrew a metal plate on it, doing this would expose to red buttons that would need to smashed; after these two buttons were smashed, the Mega AMP would go out of control and it's Kritter pilot would leave the cockpit of the Mega AMP and begin attacking by throwing bombs. Hitting the Kritter pilot would defeat and ultimately destroy the Mega AMP.
