Harry Tigon, Bobby Liger, and Mac Zonkey are hybrid animal characters made from shells, rocks, and shark teeth found on the beaches of Venice, Florida (oh, and paint). Tigons, Ligers, and Zonkeys are actual animals but not found in nature. Perhaps you would find them in Zoos, Circuses, or an episode of The Tiger King. Venice, Florida is historically known for being a circus town (formerly for Ringling Brothers Barnum and Bailey) so it is fitting that these characters are made from shells from Venice.
A Tigon is the offspring of a male tiger and a female lion. A Liger is the offspring of a male lion and a female tiger. A Zonkey is a cross between a zebra and a donkey. So, not animals you would normally see.
