Explore all the black ones, and each will awaken a mummy. However if your sim does not have these skills, there is an area in the sphinx that has 3 black pools and 1 purple one. The higher your martial arts and body skills are, the smaller your chance of losing a fight with a mummy and getting cursed are. His martial arts and body skill are so high, he will almost always defeat mummies. Sadly, Arthur has a very slim chance of ever being cursed again. A simmer on my thread requested I do a post explaining how to get cursed.
