Scarab believes the Tree of Life can make him younger again, so he hires Bes to get the Tree for him. Bes uses magic and a tree moving machine to move the Tree of Life, but never said anything about promising delivery to Scarab. With the Tree of Life removed, every living thing gets old … plants age, milk goes sour, and all the people in the city get very old. Presley looks like one of the seven dwarfs with long white hair and a beard. Even Scarab gets wrinkles on his wrinkles and later grows a beard. The Mummies are of course immune, since they are not alive. It is up to them to save the day.
