During the final battle at Horror Hall, She-Ra uses the same tricks and lines about skates and a circus as He-Man did in Three on a Dare (1984).
Adora is not in this episode. She is in She-Ra form for the entire duration.
The creature that captures Glimmer is a recolored version of Yog from Song of Celice (1983). Yet another version was seen in The Cold Zone (1985).
Script was approved May 19, 1986 and final script revision took place May 21, 1986.
