Tree O'Clock Rock - S1.E31

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.
