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 at opposite sides of the screen, each holding 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 is not as simple as firing pesticide towards the player's opponent. The insects move up and down the screen, forcing the player to do the same if to succeed. Also, each of the two characters have a limited supply of pesticide, which can be refilled; however, the player's back is turned while the player is refilling, rendering them 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 replaces him for the Modern Mode of Greenhouse in Game & Watch Gallery 3). Mario and Donkey Kong also have bubble shooters instead of pesticide sprayers. Lastly, the bugs have been replaced by a fireball and a Boo. The fireball remains in place until pushed away by the bubbles. The Boo attempts to sneak up on either Mario or Donkey Kong when one of them is busy refilling their bubble shooter. Misses cannot be removed in this game, so players will have to be cautious while playing.
