The Zonkey —
I believe that I may have a new creature to add to my tall-tale creature gallery:
The Zonkey. It's a cross between a zebra and a donkey. Except it's real, so therefore it doesn't actually qualify for entry into the gallery. The zonkey's name is Alex, and he was born on Barbados. And exactly how did he get sired? Well, apparently there were only two zebras on this farm in Barbados, a male and a female. The male got sick, so the female "became friendly with a donkey". The result was Alex, the zonkey. They just had to name him Alex, didn't they. (thanks to Teddy for the link)
