Camera
From PinataIsland.info, the Viva Piñata wiki
Trouble in Paradise
The Camera tool in VP2 is used to take photos of your garden. These photos can be uploaded to VivaPinata.com.
You can also create Piñata Vision cards for pinatas or other items in your garden. You can share these Piñata Vision cards with friends, who can scan the card with their Xbox Live Vision camera, and the pinata or other garden item will drop directly into their garden.
