Pet Rock

Bringing back the Pet Rock, popular since 1975.
Easy to care for. No need for expensive food or surprise vet bills.
Got a great personality, but can be stubborn and difficult to train.
Very low maintenance, but do generate a lot of poop in the beginning.
If your pet rock is lost it's easy to create a clone.
