Only 2 Tiberium (size doesn't matter) can be sold for the duration of this challenge. For example, you can sell only 2 large, or 2 small, or 1 large and 1 small. If you get more, you must delete the extra ones ($0).
They may adopt one dog to sniff out collectables. They must pay for it. You are required to remove $250 from the family funds after adopting. Take your current household funds and minus 250. Then use the familyfunds cheat and enter the answer. If you adopt a dog and don't take out the funds, the challenge is considered failed.
They can buy the Gem cutter when they can afford it.
Once the last sim of this generation dies, everything they've collected from the above list must be immediately sold. You also must get rid of your dog.
