At the beginning of the season one He-Man episode "The Time Corridor" we see Skeletor and his ever-present henchmen hatching there latest nefarious plot. The most interesting thing about this scene is that Skeletor's Throne Room has completely altered in appearance when compared to previous episodes; the table is now smaller with two stone blocks acting as chairs. If you look carefully you will see that Skeletor's throne is now twice the size of the Lord of Destruction! I have included a comparison shot from "Diamond Ray of Disappearance" so you can compare the two, but you will notice that now Skeletor stands on the part of his throne that he should be sitting upon!
