The Peanut Popguns are weapons in Donkey Kong 64. Diddy Kong can buy them from Funky Kong's store in the game. Their appearance is that of two small pistols made of bamboo. They are used, among other things, to shoot enemies, Peanut Switches, and Banana Balloons. In the level Fungi Forest, homing ammo can be acquired for the popguns. He also can use these guns while using his rocket pack.
This projectile weapon is also Diddy Kong's Neutral B attack in Super Smash Bros. Brawl. The Peanut Popgun fires out peanuts that hit the opponent. The player can boost the speed and lower the angle of the shot by holding down the button. If the player holds the button down too long, the Peanut Popgun will explode, briefly stunning Diddy Kong, but otherwise not dealing any damage. The shelled peanuts shot out may break, dropping a small edible peanut, which will recover a small amount of damage when eaten. Interestingly, the Peanut shells fired from the Popgun count as items and thus can be caught and thrown back. The Popgun is fully charged when Diddy reaches up and grabs his hat. If the player wants to fire a fully charged peanut without stunning the character, they must release the Special button as soon as Diddy grabs his hat.
Diddy Kong also uses these firearms in Donkey Kong Country Returns, Donkey Kong Country Returns 3D and Donkey Kong Country: Tropical Freeze. In these games, they resemble barrels. In multiplayer mode, he uses them to stun enemies, as well as defeat weak enemies (the latter one only in Donkey Kong Country Returns and Donkey Kong Country Returns 3D).
Trophy Description in Super Smash Bros. Brawl
A unique firearm that only Diddy Kong can use. It's made of a chunk of wood and shoots peanuts. In Donkey Kong 64, he carried two pistols and could fire two shots at a time. In Smash Bros., the peanut ammo bursts out of its shells when fired. The peanuts can be grabbed and eaten to reduce damage. The longer the gun is charged before firing, the faster the peanuts fly.
