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 will be able to use Rocketbarrel Boost in the upcoming Super Smash Bros. Brawl. Rocketbarrel Boost will be Diddy's Up special move, and will allow him to fly using his Jet Pack. Diddy Kong can charge this attack up, and if it is charged, he will be able to fly farther. Tilting the control stick allows Diddy to curve his flight path, allowing him to fly in several differant directions. It causes damage to anyone who hits it. However, if Diddy Kong is attacked while flying, he will lose his Jetpack, and fall down. The jetpack will then fly away, and has a chance of hitting another player.
