Trouble in Paradise
A never-before-seen feature called Piñata Vision allows players to plug in an Xbox Live Vision camera to create custom piñata cards that they can collect and trade with friends. With Piñata Vision, gamers can simply flash a piñata card up to the Vision camera, and the piñata, plant, tree, object or accessory will drop directly into the game.
