Sentinels of Time

Chuck, Sue, Sandy and P.O.P.S. are brought by the Mud People into their cave where they encounter the Sentinels of Time – small, white glowing firefly-like creatures which can freeze people in time. Chuck and Sandy are suspended in time by the Sentinels who then chase Sue deeper into the cave, where she succeeds in repelling them upon discovering they can't stand her anti-deodorant spray. Her triumph is short-lived when she finds Chuck and Sandy have been unfrozen only to have the Mudmen expose them all to a mysterious mist putting them to sleep, not to awake for ten centuries, and P.O.P.S. is unable to help them, his battery running down from no access to solar power.
