Jacko Monkey The original jacko-Monkey traces back to a 19th Century French children's story where a monkey named Jacko-Na-Ni was in love with a cat named Puss-La-Ni. To show the world their love, they danced the polka together. If you want to see an example of what how he originally looked, I was able to track down only a single example, but you can see the two right here:
