Greenhouse

Greenhouse (released as Green House) is a dual-screen Game & Watch game released as part of the Multi Screen series on December 6, 1982. It is featured in the Museum in Game & Watch Gallery 2. It was later remade for Game & Watch Gallery 3 with a Classic version and an updated "Modern" version.

The alarm indicator of this game is a cat that is located in the lower screen, beside the ladder, and a bee stings the cat when the alarm goes off.

Classic version
The player controls Stanley, and the objective is to spray inchworms and spiders that try to eat the flowers in a greenhouse. The inchworms crawl along vines on the top screen, while the spiders crawl along webs on the bottom screen, and the player has to try to hit them with a spray gun before they reach the flowers. A ladder connects the two parts of the game (which otherwise offer almost identical action). The player receives a point for killing an inchworm far from a flower, two points for an inchworm one step away from a flower, and three points for an inchworm closest to a flower. To kill the spiders, however, the player needs to spray them closest to a flower. If sprayed farther away, the spiders back away one step, giving the player a point. When the player kills a spider, they earn three points. As the game progresses, the inchworms and spiders move faster. If an inchworm or spider reaches a flower, the flower dies, earning the player a miss. If the player gets 300 points without any misses, all points are worth double until the player does get a miss. If the player has any misses at said score, all misses are canceled instead. When the player gets three misses, they receive a Game Over.

Modern version
In the Modern version of the minigame, an Orange Yoshi has to protect his flowers by spraying Fly Guys and Grinders with watermelon seeds (as he did in Yoshi's Island). The tulip that releases Stars from Yoshi's Island releases the Fly Guys. In this version, a Warp Pipe connects the two parts of the game. The Yoshi earns a point for defeating a Fly Guy and three points for a Grinder. In addition to the points earned for defeating the enemies, the Yoshi also receives a point for every watermelon he eats. Once the Yoshi grabs ten watermelons without getting a miss, he gains fire-spitting powers, allowing him to burn the ropes of the Grinders, scorching them even while they are shielded, and the Yoshi earns three points for defeating a Fly Guy. If a Fly Guy or Grinder reaches a flower, the enemy jumps on it and kills it. At 200, 500, and 700 points, a heart appears for the Yoshi to remove a miss. Music is also featured in this version, with the tempo changing depending on the speed of the game.

However, in this version, the score and miss marks alternate positions depending on the section the Yoshi is standing on.
