A video game released in 1991 from Hudson Soft starring the prehistoric caveman Bonk unleased the TurboGrafx-16's mascot on the world. As Bonk you traveled around the prehistoric land fighting baddies by bonking them with a fierce headbutt. The headbutt grew stronger if Bonk ate pieces of meat that were found inside of flowers. Some flowers also contained smiley faces, and collecting them yielded bonus points. Other flowers enabled Bonk to super junp, but others contained hidden baddies and moreover, some flowers were just empty. The plot of the game follows Bonk as he tracks down King Drool who has kidnapped Princess Za, the moon princess.

The series began on the TG16 console (and spawned two sequels that had more of the same type of gameplay) and eventually crossed over to the Super NES, NES, and Game Boy. The Game Boy version, while fun for all ages, seemed aimed at the kiddie market as the dialogue scrolled by obscenely slow and was not capable of being sped up. Furthermore, said dialogue was written in short, simple sentences with no complex words. Then again, this could be a fault of the translators when the game was ported from Japan.

A spin-off series starring a futuristic robotic Bonk, named Zonk, didn't last very long. In fact, the only game in the series was Air Zonk, a side-scrolling shoot-em-up based on Gradius. It was released solely for the TurboGrafx-16.
