Donkey Kong 3 (Game & Watch)
Just like in the original arcade version, Donkey Kong breaks into Stanley's greenhouse and goes to hang in the rafters where he stirs up nests of Buzzbees and Beespies, which will destroy Stanley's flowers in revenge. Armed with a can of fly spray, Stanley must destroy the bees and chase Donkey Kong away before he wrecks the whole greenhouse.
Stanley and Donkey Kong are both at one side of the screen with a can of pesticide. They must each use their can to push insects towards their opponent. After an insect successfully reaches one side of the screen, the character on that side will get bitten or stung (Uncertain due to the Game & Watches graphical capabilities). However, the objective was not as simple as firing pesticide towards your opponent. The insects would move up and down the screen, forcing the player to do the same if to succeed, and they each had a limited supply of pesticide, which could be refilled, although when refilling, the player's back is turned, rendering him or her defenseless.
The game was remade as part of Game & Watch Gallery 4 with a few differences. First off, Mario replaces Stanley (just like how Yoshi replaced him for the Modern Mode of Greenhouse in Game & Watch Gallery 3). Mario and Donkey Kong also had bubble shooters instead of pesticide sprayers. Lastly, the bugs had been replaced by a fireball and a Boo. The fireball would remain in place until pushed away by the bubbles. The Boo would attempt to sneak up on either Mario or Donkey Kong when one of them were busy refilling their bubble shooter. Misses cannot be removed in this game, so players will have to be cautious while playing.
