Day of da Spookies was never made. You can find scripts for it though, so I've posted some quotes and updated the character list for it.

The basic premise of this episode is that Zim realizes the reason Dib is a constant problem is because of his paranormal beliefs. Zim sets out to find a way to make Dib relinquish his paranormal beliefs - and comes up with the idea of dressing himself, GIR and Minimoose up as ghosts and having Dib report them to Mysterious Mysteries. Zim would then reveal that it was all a fraud and Dib would be discredited and disheartened…in theory.

In practice, they DID get Dib to believe they were ghosts and he DID bring in Mysterious Mysteries, but Mysterious Mysteries sent a paranormal expert to examine them to see if they were really ghosts. Zim managed to get rid of the expert ("GIR - throw him into space!") but their paranormal expert replacement (Invader Skoodge in a poor costume) wasn't very convincing. In the end GIR and Minimoose escape, Dib is discredited but Zim is put into a ghost bucket for extensive and painful testing.

My Favorite Moments:

I like to see the return of Invader Skoodge and I think it's funny that he's sent to Earth to get rid of him. I also think it's funny that GIR throws someone into space.
