3D Pets is a game where the player takes care of a variety of different creatures.

Each 3D Pet begins its life upon hatching out of an egg (yes, a dog hatches out of an egg!) and must be cared for at least 10 minutes per day. If you are unable to play with your pet there is a babysitter feature that does so until you return.

PC Pup is the second half of the first volume in the series, alongside Splat! The Cat.

Once you name your pup, you are free to explore a handful of interactive rooms including a bedroom with a stereo, bathroom with medicine in case the pet gets sick, living room with a television, and a garden where your pet must be trained to 'do its business', as well as others. Little thought bubbles will appear over PC Pup's head indicating what he wants the player to give him, or how he is feeling.

At the end of the pets lifespan, you will see him shrink slowly and then be presented with an 'Angel's Certificate' with stats about the pet's care listed. You may then hatch your next pet and let the circle of life continue.
