She-Ra: Princess of Power (1985)

S1E20 Three Courageous Hearts

Disguised as a young woman, Shadow Weaver slips into Mystacor’s festivities, casting a sleeping spell over the rebel guests. She then hurls She-Ra into a strange sixth dimension, leaving her stranded. With everyone else unconscious, only Kowl, Madame Razz, and Broom remain awake to mount a rescue—a quirky trio forced to outwit the sorceress and bring their friend back before the spell becomes permanent.
