ThinkGeek USB Pet Rock
Solid companion, no care required.
Bring a much loved retro classic into today with the USB Pet Rock. This blast from the past meets the modern era with an integrated USB cable that measures a full 18 inches. But, you have no need to fear yet another drain on your system. Just like its classic counterpart, it actually uses nothing. That’s right, no food, water, or even power. With the natural differences, each pet is as unique as the owner.
