The game's protagonist is Bonk, a strong caveboy who battles dinosaurs, particularly the lizard King Drool, who has kidnapped Bonk's friend Princess Za. Bonk can use pieces of meat as power-ups, these lend him special abilities and make him stronger. There are three stages of powerup: his normal self, a second stage during which he can stun enemies by pounding on the ground, and third stage where he becomes temporarily invulnerable. In the original game, the second stage turns Bonk into a caveman, but in Japanese versions of the second and third game, he becomes a cavewoman. This gender transformation was scrapped for the US entries in the series. Another unique facet to the game that was kept in all versions was how Bonk climbed trees. Since ladders were not used in prehistoric times, Bonk is shown biting the tree to gain leverage. Also unique was that some bosses were revealed to have been hypnotized by King Drool, or bamboozled into being his slaves, after Bonk defeats them, such as the first boss, whom Bonk realized was a friend of his put under Drool's spell.
