Throw Mummy from the Train (S02E15)

A greedy assistant archaeologist, Dr. Denton Wexler, ignores an ancient curse when he steals a jeweled ring from an Egyptian Tomb, thereby bringing the Guardian Mummy to life. By accident, the ring gets stuck on Dale which sets the mummy after the Rescue Rangers. The archaeologist manages to recover the jewel, and hops aboard the train to Cairo, leaving the mummy and the. Rangers in the dust. That's when the mummy (a sympathetic Herman Munster-type) hires our heroes to help him recover the ring. A shortcut via camel enables the mummy and the Rangers to board the train enroute so they can search for Dr. Wexler. Wexler thinks the ring will lead him to the Pharaoh's treasure hidden under the Sphinx. (iTunes)
