In J. Michael Straczynski's original notes for this episode, he described Modulok as having two heads and lots of spare body parts, like the toy. However, this design was too complex for Filmation to animate and so they simplified him. His extra head was later seen in "Happy Birthday Roboto".
At the end when the lesson of the episode is being told, Adam is clearly speakng in He-man's voice.
This episode contains a direct reference to the earlier episode "Double Trouble", also written by Straczynski. Careel is seen telling Tharen about how He-Man saved the village of Cathenay from Sand Demons- the battle she is talking about was seen in "Double Trouble".
It seems a bit strange how Skeletor is so quick to refuse Modulok's services- when he'd allow bumbling fools like Trap Jaw, Spikor and Two Bad into his army, you'd think he'd be more willing to recruit someone of Modulok's intelligence!
Teela: Well, I guess it's about time we got back to the palace. Where's Cringer?
Orko: I don't know, he's been gone a long time. I hope he didn't go wandering into the forest.
(Cringer runs by frantically)
Teela and Adam: He did go wandering in the forest.
