Keep a pet, you can wait for the pet to lay its eggs. If the color of the pet egg is very good, you can photograph it and sell it, but only if it is very good. The color quality and value of this pet egg are determined by the attributes of the pet egg. The attribute level of the pet egg is determined by the attribute values of the parents of the pet egg. Therefore, only well-kept pets can sell their own pet eggs. Ordinary attribute values are of little value. I don't feel like it used to be. It was hard to find a pet before, because it was hard to get one by yourself. Now basically everyone has a pet, and it's easy to break eggs. Therefore, pet eggs with average attribute values are basically unknown. Especially pet penguins, pet pigs are better. However, because the supply of pet bears is limited, it is hot in the market now. If you have a pet to earn money, you can keep a pet bear.
