Bonk can turn into one of three unique heroes: Master Bonk, Hungry Bonk, or Stealth Bonk. Becoming Master Bonk dresses Bonk in a cape and provides him with Vulcan-esque ears, and gives him the ability to move faster and jump higher. Becoming Hungry Bonk gives Bonk an animalistic appearance with evil eyes and a mouth full of razor-sharp teeth, and gives bonk the ability to chew enemies to death, as well as providing him with a much stronger head-butt that can kill nearby foes. Becoming Stealth Bonk dresses Bonk in a striped jail outfit, and gives him the ability to enter special locked doors that lead to areas such as the bank, where Bonk can collect Smileys, the butcher's, where Bonk can eat more slabs of meat in hope for a different power-up, and jail, where Bonk loses a portion of his Smileys.
Grabbing one of many tulips scattered throughout the game carries Bonk to a special bonus stage where he can face off against Mechabonk -- a RoboCop-esque version of Bonk—in a best-of-three battle to "bonk" one another off the edge of a small stage. Winning two rounds provides Bonk with an extra life, while a loss transforms Bonk into Wounded Bonk, where Bonk resembles a mummy and takes twice as much damage as usual.
The game overall is very similar to games in the Mario series, providing linear, side-scrolling action, multiple power-ups, and several small boss confrontations leading up to a final boss. Its treatment of power-ups is similar as well: taking a hit while powered-up causes Bonk to take no damage but instead lose his power. For those who struggle with the game, the game offers passwords after game-overs so the player does not need to start over from the beginning.
The fourth game in the regular "Bonk" caveman series, Bonk is back on his first Super Nintendo outing.
In this side-scrolling platformer adventure, the gameplay is similar to Bonk 3. Super Bonk allows Bonk to travel through time from his prehistoric levels, the insides of a dinosaur, a version of modern Chinatown, and even the moon! Along the way, Bonk can find power-ups that can change his form to creatures such as a shooting Bonk crab, a dinosaur form called "Big Kronk", find candies that change his size from tiny to huge, travel through transportation tubes, and find multiple bonus levels.
Bonk still uses his head to smash his enemies, propeller seeds that allow Bonk to fly, and for the first time, can carry spring flowers on his head in his continuing battle against his arch nemesis, King Drool!
