Sprayer

The Sprayer, also formatted sprayer and alternatively named spray gun or , is a weapon used by Stanley in Green House and Donkey Kong 3 as well as Mr. Game & Watch's primary weapon in the Super Smash Bros. series.

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

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

Donkey Kong 3 (Game & Watch)
In the Game & Watch version of Donkey Kong 3, in the same fashion as in the arcade game, Donkey Kong stirs up nests of bees, 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 bees 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 repellent (as it is generically referred to in the Stanley trophy) belongs to Mr. Game & Watch, who uses it as his standard attack; this attack is called Greenhouse, and it deals only 1–3% of damage.

The Greenhouse attack returns in Super Smash Bros. Brawl and subsequent Super Smash Bros. installments. In Super Smash Bros. Ultimate, Mr. Game & Watch's appearance changes while using the attack.

Game & Watch Gallery 4
In the Modern version of the Game & Watch version of Donkey Kong 3 in Game & Watch Gallery 4, Mario uses the repellent to push fireballs and Boos towards Donkey Kong. It sprays bubbles and needs to be refilled with water.
