'''Bonk's Adventure''' (also known as '''PC Genjin: Pithecanthropus Computerurus''' or '''B.C. Kid'''), is the first game in the ''VideoGame/{{Bonk}}'' series, a PlatformGame created by Red Entertainment and Hudson Soft in 1989 for the ''UsefulNotes/Turbografx16''.

The Evil King Drool is wreaking havoc, having kidnapped the Princess Za of the Dinosaur Kingdom, and brainwashing many dinosaurs with mind-control helmets, and now its up to a little caveman named Bonk to save the day. In a dangerous world filled with enemies, there unfortunately isn't a lot of weapons around. So our hero will just need to use his head. Literally.

''Bonk's Adventure'' is a standard 2D plaformer with a slight twist on the gameplay. Bonk's weapon is his enormous hard head, which he uses to headbutt and slam down on the enemies he encounters. Bonk can gather food items like fruits and vegetables, which restore his health meter. But the heavy hitter item of ''Bonk's Adventure'' is Meat. Bonk grows stronger and more powerful when he eats meat, with small pieces powering him up and large chunks making him temporarily invincible. Bonk can also play various bonus rounds that reward him with greater points and extra lives.

''Bonk's Adventure'' was a solid hit for the Turbografx and it received several sequels and many remakes and ports, including a TwoAndAHalfD remake for the Gamecube and Playstation 2. Bonk also went on to become the mascot of the console itself during its lifespan.

The game was followed by a sequel ''VideoGame/BonksRevenge'' in 1991.
