Yes, Tarzan's friend in the long running comic strips was indeed a small monkey, not a chimpanzee, and his name was N'kima. The Hollywood movie people thought that American audiences were too stupid to handle a slightly complex name like N'kima, so they renamed the monkey "Cheetah", and replaced him with a young Chimp. So now almost everyone thinks of the movie version..."Cheetah"...rather than the comic magazine version...N'kima.

It's sad. Hollywood does everything they can to keep Americans as ignorant as possible, and with considerable effect, unfortunately!

And no, you are not the hereditary Lord Greystoke. But if it makes you happy to think so, why should I stand in your way? Enjoy your fantasy. Buy a banana suit. You can get them on Amazon.
