Greenhouse

Greenhouse (originally spelled Green House) is a Game & Watch game released on December 6, 1982. The player controls a bug exterminator only referred to as the "Fumigator" in the manual, and the objective is to spray worms that try to eat the plants in a greenhouse. The worms crawl along vines and the player will have to try to hit them with a spray before they reach the plants (which would then die). The game is a two-level one with a ladder connecting the two parts (which otherwise offer almost identical action). The game is relatively easy to begin with but soon gets harder.

In a 1983 Game & Watch commercial, the Fumigator is called "Stanley," which is the name of the playable character featured in the Donkey Kong 3 arcade game released that same year. Donkey Kong 3 is also set in a greenhouse and has similar gameplay; however, Nintendo has never officially connected the two titles, and Stanley does not resemble the Fumigator.

In the Modern version of the minigame, an Orange Yoshi has to protect its plants by spraying Fly Guys and Grinders with watermelon seeds (as it did in Yoshi's Island). To play, the player must use the to move and  to shoot watermelon seeds. Once the Yoshi grabs ten watermelons, it will gain fire-spitting powers, allowing it to burn the ropes of the Grinders, scorching them even while they are shielded. The tulip that releases stars from Yoshi's Island releases the Fly Guys. The Classic Mode of the game does not deviate from the original Greenhouse.
