is an arcade game released in 1985 by UPL. It was ported to the original Game Boy (1990), MSX and Famicom by ASCII under the title Penguin Wars. The Game Boy version of the game is known as King of the Zoo in Europe and Penguin-Kun Wars Vs. in Japan. The main background music in most versions of the game is an electronic rendition of a song originally performed by 1980s J-Pop singer (in turn a translation of "The Glamorous Life" performed by Sheila E.).

If a player is hit by one of the balls, they are knocked unconscious for a certain amount of time. Thus, it could also be said that part of the object of the game is to hit the opponent, as otherwise it would not be possible to get all ten balls to the other side (the opponent can just roll them back before all of them have arrived). The different animals have different strengths and weaknesses which are a trade-off with each other. For example, the rat is the one that can move left and right the fastest, but in return he can roll the balls only very slowly. The cow, on the other hand, is a very slow walker, but in return she regains consciousness more quickly. After thirty seconds of playing, a jellybean-like obstacle appears in the middle of the table which moves left and right. Different kinds of
