Who's Whom Here?

Dr. Strange discovers what has happened to P.O.P.S. and his friends, and through one of his inventions, tries to transport them out of their bodies to his cave. The process fails due to a sudden short circuit, but the exposure to solar energy rejuvenates P.O.P.S., enabling him to free Chuck, Sue, and Sandy from their sleep spell just in time for them to save him from being crushed by falling rocks. However, the whole process has some side effects, including the accidental transportation of mysterious beings from another dimension over to the island and, as the trio and their robot escape the cave, Chuck somehow undergoing a body switch with Krieg.
