Going Bananas

From the Super Mario Wiki
“Not only that, but you won't take any damage! It's called Going Bananas!”
Cranky Kong, DK: King of Swing
Donkey Kong uses his Going Bananas power

Going Bananas is a move in DK: King of Swing that is learned in Cranky's Lectures. This move can be activated by pressing the A Button button when the player has twenty bananas. When activated, Donkey Kong becomes invincible, but only for a short amount of time. When in use, Going Bananas can help Donkey Kong break through multiple barrels at one time. It also makes Donkey Kong faster and quicker.

In DK: Jungle Climber, Donkey Kong can perform a very similar move if the player taps a Crystal Star on the bottom screen. The theme that plays is also similar to the Going Bananas theme.
