Rocketbarrel Boost

Rocketbarrel Boost is an attack that Diddy Kong can utilize once he drinks one of Cranky Kong's potions in Donkey Kong 64; once Diddy jumps into a barrel with his face on it, he will gain the Rocketbarrel Boost, a jetpack, and be able to fly around using his Peanut Pop Guns. This attack utilizes Crystal Coconuts as fuel. However, this ability is also barred in a few sections of the game. In both Mario Power Tennis and Mario Hoops 3 on 3, Diddy is also capable of using the Rocketbarrel Boost to fly.

Diddy be able to use Rocketbarrel Boost in the upcoming Super Smash Bros. Brawl. Although, it has not been seen, nor has it been confirmed which move it is (Standard B, Up B, etc.). Rocketbarrel Boost is believed to be his Up B move, however, this is unconfirmed.
