Greenhouse was a Game & Watch starring Stanley the Bugman from Donkey Kong 3. The objective was to spray worms that try to eat Stanley's 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 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.
