Sprayer

The , also known as the spray gun, sprayer, is Stanley's weapon of choice throughout his scarce appearances, as well as Mr. Game & Watch's primary weapon in the Super Smash Bros. series based on its original appearance in Green House.

Green House
In its first appearance, the spray gun can be sprayed an unlimited number of times. It is used to kill the worms and spiders that try to destroy the Fumigator's flowers before they do so.

Donkey Kong 3
In Donkey Kong 3, Stanley must use the weapon against Donkey Kong and the angry bees and other insects that will try to destroy his vegetables. Once again it can be sprayed an unlimited number of times. Its power can also be amplified by equipping the Power Spray, which changes the insecticide to a yellow color; however, this is only a temporary power-up.

Donkey Kong 3 (Game & Watch)
In the same fashion as in Donkey Kong 3, Donkey Kong stirs up nests of bugs, so Stanley is required to use his sprayer to combat Donkey Kong, who now has one of his own. The spray works differently here, as shots trap the bugs and cause them to fly towards the opponent. They have to constantly be refilled with insecticide by a dripping pipe nearby. While refilling the sprayer, the player will be left defenseless.



Super Smash Bros. series
In Super Smash Bros. Melee, the insect repellant belongs to Mr. Game & Watch, who uses it as his standard attack. The attack performed by it is called Greenhouse, and it deals 1–3% of damage.

The Greenhouse attack returns in Super Smash Bros. Brawl in the series and continues to be used as a trademark attack. In Super Smash Bros. Ultimate, Mr. Game & Watch's appearance changes while using his standard attack.

In a modern update of the Game & Watch version of Donkey Kong 3, Mario uses the repellant to push fireballs and Boos towards Donkey Kong. It sprays bubbles and needs to be refilled with water.
