Space Rocks (Collectibles)
Space rocks are found only in outer space so to collect them, you need a rocketship. As you are exploring space and going on adventures, you will occasionally find a space rock and bring it back home. You can put them on display or keep them in your inventory. You can also sell them, but then you don't get a lot for them compared to the effort to get them. There are only four different space rocks to collect.
Space rocks make great decor and add a lot to a positive environment for your Sims. Plus they just look cool. Maybe that unnaturally large space rock should go out into the yard though. As you can see from our picture above, it lives up to its name!
