Even the heroes in a half shell couldn't have stopped one Canadian college student from ending up in a prison cell.
The man attempted to get past the United States border with 51 turtles in his pants, before he was arrested in Ann Arbor, Michigan on smuggling charges.
Kai Xu pleaded guilty to transporting the poor turtles and now faces a maximum penalty of 10 years in prison.
He's also admitted to smuggling or attempting to smuggle more than 1,600 reptiles out of the U.S. within a six month period.
The University of Waterloo student was already under surveillance when he picked up a box at a UPS.
U.S. agents then saw him hide behind trucks and transfer the contents to his pants.
After emerging with "irregularly shaped bulges" in his sweats, authorities eventually searched him at the Canadian border. They found 51 live turtles taped to and in between his legs.
Apparently, he would order turtles online, visit the states to pick them up and bring them back north or send them to China.
U.S. officials say in China, the turtles are worth two to three times the amount he pays here.
Starting at around $1,300 dollars per turtle, that's a lot of money, but illegal smuggling?
That sounds more like Shredder's racket than Donatello, Michelangelo, Leonardo, and Rafael's.

In this photograph taken on April 20, 2010, four month old Hawksbill turtles swim into the sea after a symbolic release by conservationists at the Thousand Islands National Marine Park in Pramuka island north of Jakarta. Hawksbill turtles, known by their scientific name Eretmochelys Imbricata, are listed as an endangered species by the International Union for the Conservation of Nature and Natural Resources. Hunted for their flesh, shell and eggs, plus destructive fishing methods have threatened the survival of the sea turtle. Indonesia's conservation efforts include aiming to stop the illegal trade of Hawksbill turtle products and protect its natural nesting grounds.
