In 1982, Taito released an arcade game named Jungle King. The main character was a vine-swinging, loin-cloth-wearing, damsel-rescuing jungle dweller with a very distinctive yell. Seem familiar? The estate of Edgar Rice Burroughs thought so, and they sued Taito for infringement of their copyright to Tarzan. Taito responded by turning Jungle King into Jungle Hunt, replacing the Tarzan look-alike with a British explorer, complete with a pith helmet and khaki shorts. The rest of the game remained the same, tasking our hero with navigating a jungle full of swinging vines, an alligator-infested river, a hillside of falling boulders, and finally a cannibal luncheon, all to rescue his fair maiden. The new, Tarzan-less game proved less likely to inspire lawsuits, and went on to become a respectable hit for the company that had unleashed Space Invaders on the world.
Taito wasn't quite through yet, however, and before the year was out, yet another clone of Jungle King was making the rounds, named Pirate Pete. This time a few more graphics were changed, with the jungle vines becoming ropes on a pirate ship, and the river of alligators becoming an ocean of sharks. The game again remained the same, making Pirate Pete the third game to use the code created for Jungle King. Of those three, Jungle Hunt remains the best known, thanks in part to Atari's conversions for several home computers and game consoles, from the Commodore 64 to their own Atari 2600.
