His weapon is the Pineapple Launcher, his instrument is the Triangle Trample, and the potion enables him to do Hunky Chunky; turning gigantic and invulnerable for a short period of time. His special ablities include the Primate Punch (which unleashes a very powerful punch which can smash down some doors and walls), his Burp Skill (in which he releases a giant belch and pats his stomach), and Gorilla-Gone (turning temporarily invisible). He can carry boulders and other heavy items that the other Kongs cannot carry. It should be noted that it was Chunky, with a combination of the "Hunky Chunky" and "Primate Punch" abilities, who defeated K.Rool in the last boxing match in Donkey Kong 64.
