Continuity mistake: During 'Dance Magic Dance,' when Jareth sings "Then baby said...," behind him, beside the large clock, there is an axe leaning against the wall. In the following overhead shot it has gone. In addition, a large dancing goblin, wearing an all black outfit appears in front of the large clock between the same two shots. (00:22:55)
Suggested correction: Top picture: If you look just to the left of the circled goblin's left shoulder, you can see the hand of the other goblin holding the axe in question, clad in green.Lower picture: You can see the handle to the axe still next to the goblin in question's feet, and the blur next to his head must be the axe's top. It's a blur because he must be twisting it as he dances the magic dance.
