When Two-Bad appears, he's changed. Tuvar (the blue guy) is in the left and Baddhra (the purple guy) is in the right.
This episode features an unusual addition to the Royal Palace - the Rainbow Tunnel, apparently built by King Randor for Adam and Teela to play in when they were kids.
Modulok is seen among Skeletor's crew here- but it doesn't explain how he has managed to make it into Skeletor's army. In "Mistaken Identity" Skeletor said he would only let him join up if he could seriously impress him- so what has Modulok done to finally convince Skeletor to recruit him?
When He-Man tells Mekaneck about the Rainbow Tunnel, doesn't it seem at all suspicious that He-Man would know about the tunnel, when Mekaneck doesn't know He-Man is Adam? But then, Mekaneck is portrayed as completely dumb here...
Mekaneck's voice- and his personality- differ radically here from his other episodes. He is given a high-piched, squeaky Orko-esque voice which is totally unsuited to him, and character-wise he is portrayed as stupid, dim-witted and useless, making a fool of himself with every line!
He-Man: Ready, boys!
He-Man clones: READY!!
