Monkey Puncher (さるパンチャー, Saru Panchā) is a video game for the Game Boy Color, developed by Taito Corporation, and released in December 2000. The game's goal is to train a monkey to fight in organised boxing matches in order to save the main character's father and sibling.
At the start of the game, the player must choose to play as either Kenta (male) or Sumire (female). While the choice has little effect on gameplay, the sibling who is not chosen is the one kidnapped. Shortly after the beginning of the game, the player is given his first monkey, called Freddy, to train.
After obtaining the first monkey, and any subsequent new monkey, the player must befriend it by offering it food before he/she can begin training it. Over time, the monkey becomes more and more friendly towards the main character.
The monkeys are trained in skipping, using a punchbag, doing sit-ups, running and going shopping. These activities increase, respectively, the monkey's speed, power, strength, stamina and knowledge. In addition, a fifth option, sparring, has the potential to increase all statistics, albeit by a smaller amount.
In skipping, punching, sit-ups, and running, the monkeys learn to train by
