Both Beast Man and Mer-Man have lost their chest armor and Mer-Man is noticeably scarred, like well-played with action figures.
On the chest besides Orko's bed are displayed the 'Hero' medal he received during the flashback scene in Creatures from the Tar Swamp (1983) and a Trollan magic pyramid surrounded by some small pieces of meteorites, the combination of which allowed Dree Elle to travel to Eternia in Dawn of Dragoon (1983).
The ship seen during the opening flashback resembles the Sea Eagle from the 1984 Masters of the Universe Ladybirds Book Skeletor's Ice Attack.
Although not mentioned on screen, in the flashback sequence He-Man's hands are bound by cuffs made out of Coridite, the powerful substance that first appeared in Evil-Lyn's Plot (1983).
Kevin Smith said that this episode was a homage to Batman (1989)
