Stanley

Stanley is a bug exterminator who debuted in the Game & Watch game Green House. In this game, Stanley uses his spray gun to defeat hungry pests. He later became a part of the Donkey Kong franchise as the main protagonist of Donkey Kong 3, where he battles with Donkey Kong and several insects in a greenhouse with his spray. Stanley has rarely appeared since, and many of his subsequent appearances relate to his role in Donkey Kong 3.

Green House
In Green House, Stanley must defend his plants from inchworms and spiders that seek to devour his flowers. Unlike his later depictions, he appears much taller in character artwork. He wears a white cap, a red shirt, and khaki trousers. In the manual, Stanley is named the Fumigator, although promotional materials refer to him by name.

Donkey Kong 3
In Donkey Kong 3, Stanley works as a fumigator when Donkey Kong and various insects attack his greenhouse. In order to put a stop to Donkey Kong, Stanley needs to spray him and the insects with his sprayer while also trying to keep the bugs away from his plants. After pushing Donkey Kong up into a beehive, Donkey Kong flees to another greenhouse and Stanley chases after him in order to continue driving him off. In the arcade version, the bugs eat Stanley if he is defeated by one, while in the NES version, the bugs do not eat him, and instead simply disappear. His current appearance of being short, round-faced, bucktoothed, and clad in overalls is established in this game.

Donkey Kong 3: Dai Gyakushū
Stanley returns as the protagonist of the Donkey Kong 3 follow-up title, Donkey Kong 3: Dai Gyakushū. His role is very similar to Donkey Kong 3 in that he must spray Donkey Kong to the top of the screen and while also blasting the invading bees, although this time there are no plants to protect, nor are there any multi-level platforms. These changes make for something that is somewhat akin to Galaga.

Donkey Kong 3 (Game & Watch)
In the Game & Watch version of Donkey Kong 3, Stanley's greenhouse is again attacked by Donkey Kong, who this time has a sprayer of his own. Donkey Kong and Stanley stand at opposite ends of the greenhouse and spray at the bees to move them toward one another and get them to sting the other.

Saturday Supercade
Stanley made an appearance in the television series Saturday Supercade, in the Donkey Kong episode "Greenhouse Gorilla," where he is the owner of a greenhouse. Here he is seen taking care of a carnivorous plant called Herman, but then a thief (only referred once as Mr. X) steals it while Stanley is occupied with spraying a bug. The thief then convinces Donkey Kong that Stanley is the one who wanted to hurt the plant, so he starts throwing beehives at him. Once again, Stanley is too occupied fighting the bugs and lets the thief and Donkey Kong run away with Herman. Stanley then joins forces with Mario and Pauline and starts chasing them. After a confrontation at a supermarket, and one at a manor where a "grand ball" was taking place, Pauline convinces Donkey Kong that the thief is the evil one, so they finally defeat him with the ape's help. The thief is finally arrested and Herman returns to Stanley, but Donkey Kong runs away once again.

Game & Watch Gallery 4
Stanley appears in Game & Watch Gallery 4 as a playable character in a port of the Game & Watch version of Donkey Kong 3. A modernized version is featured; however, it is set in a Ghost House rather than Stanley's greenhouse, Mario replaces Stanley, and Boos and fireballs replace the bees.

Super Smash Bros. series
Stanley appears in Super Smash Bros. Melee as one of the many collectible trophies. His overalls are white instead of red but his shirt remains blue. Mr. Game & Watch also uses the sprayer as a weapon called Greenhouse, matching its first appearance, and continues to use it in later games in the series as his neutral attack.

In Super Smash Bros. Ultimate, Stanley appears as a spirit. In this game, Mr. Game & Watch's Greenhouse attack transforms him into Stanley's Green House sprite.
