S2·E50 Time Doesn't Fly

Adam, Teela and Orko are enjoying some recreation (while Cringer sleeps!) when they notice that no time seems to have passed since they began. After He-Man has rescues a young girl by from a giant underground creature confused by the stop of time, the girl turns out to be Princess Kaffay, daughter of the Emperor of Sinba. She explains that evil wizard Hexon has captured her father and the Keeper of Time, and has used his powers to effectively stop time from passing. It is written that the Emperor must appear to the Council of Seasons on the first day of Spring, and request permission to rule for another year. With the Emperor captured and the stopping of time causing disarray, Hexon plans to step in and take the throne for himself...
