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 is also able to use Rocketbarrel Boost in Super Smash Bros. Brawl. Rocketbarrel Boost is Diddy's Up special move, and allowa him to fly with only 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 different 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. The Rocketbarrel Boost is also used during Diddy Kong's Final Smash, Rocketbarrel Barrage.

Trophy Information from Super Smash Bros. Brawl
''An item that looks like regular barrels but becomes a rocket-powered jet pack when Diddy Kong straps them on his back. It's a convenient gadget to have when adventuring, but for whatever reason, Diddy also uses it when playing tennis and basketball. The moves he can pull off with the rocketbarrel pack are so cool that they're almost not fair. Almost.''
