A Bengal tiger cub shocked witnesses and zoo officials at a zoo in Northeast China when it joined another cub in a sexy romp. The couple, a 5 day old Bengal tiger and her special crane friend, seemed open to the addition. Although tigers are typically very playful as cubs, the red-crowned crane is not known for his sense of adventure. Even more shocking is the fact that the tigers are twins.
