Popgun

The Popgun is a type of weapon commonly used in the Donkey Kong franchise. Originally appearing in Donkey Kong 64, they are small, ranged weapons that shoot various types of projectiles, such as Peanuts or bubble gum.

Peanut Popgun
The Peanut Popguns are an item in Donkey Kong 64. Diddy Kong can buy them from Funky Kong. Their appearance is that of two small pistols made of wood, appearing to be hollowed out logs. 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 jetpack.

The Peanut Popgun appears in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U, as Diddy Kong's standard special move, and can be charged up. When charged up, the peanuts fired are much faster, and will have a better chance at hitting the opponents. Charging it for too long, however, leads to the popgun exploding in Diddy Kong's hands, stunning him; in Super Smash Bros. for Nintendo 3DS / Wii U the explosion can also damage opponents. The attack occasionally releases peanuts that can be eaten as food. If Diddy Kong's powers are copied by Kirby, he will also be able to use Peanut Popgun. In Super Smash Bros. for Nintendo 3DS / Wii U this move has two custom variants: Exploding Popgun, which doesn't fire peanuts and can only deal damage by exploding, which it does more quickly; and Jumbo Peanuts, which fires larger peanuts that do not travel as far and deal more damage. Diddy Kong also uses two Peanut Popguns when using his Final Smash, the Rocketbarrel Barrage.

The Peanut Popgun reappears in Donkey Kong Country Returns, Donkey Kong Country Returns 3D, and Donkey Kong Country: Tropical Freeze. It allows Diddy Kong to shoot peanuts at enemies, as usual. Enemies shot by the Popgun will become stunned, similar to Donkey Kong's Hand Slap move.

Bubble Gum Popgun
The Bubble Gum Popgun is used by Dixie Kong in Donkey Kong Country: Tropical Freeze. It works similarily to the Peanut Popgun, although instead of peanuts, it shoots bubble gum. It is a reference to Dixie's idle animation in Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Country 3: Dixie Kong's Double Trouble, where she would blow bubble gum.

Denture Popgun
The Denture Popgun is used by Cranky Kong in Donkey Kong Country: Tropical Freeze. It works similarily to the Peanut Popgun, although instead of peanuts, it shoots dentures.

Trivia

 * In beta screenshots of Donkey Kong 64, the Peanut Popguns originally looked like real guns. This was most likely changed to give the game a more child-friendly rating.
