Chimpy Charge

The Chimpy Charge (Hurtus Cranium) is one of Diddy Kong's three unqiue moves in Donkey Kong 64. Diddy can learn this ability after buying a potion from Cranky's Lab in Jungle Japes for three Banana Bunch Coins.

The Chimpy Charge can be activated by pressing and holding the button while hitting the  button. Chimpy Charge is used to activate wall switches or destroy walls.

A notable instance where Chimpy Charge is used is in Tiny Kong's room in Angry Aztec. Here, Diddy can only rescue Tiny by using Chimpy Charge on a Diddy Switch, and then the raised K-O-N-G Switches individually.
