It's a pirate turtle with a peg leg! Awwwww! According to the internets, in 1503 Christopher Columbus was the first European to come across the Caymans and he named them Las Tortugas (the turtles) after all the sea turtles in the water around the islands. And later on in the 1800s, the islands became a popular hideout for pirates. So you know, someone there got creative, combined the two things the island is most well-known for, and VOILA! You've got yourself an airplane with a giant, peg-legged pirate turtle!
