Captain N: The Game Master (Lost 1989 2nd Version Episode)

In 1989, the Captain N second episode How's Bayou was never fully complete, due to time constraints. When the unfinished episode was aired, it was heavily panned for its unfinished features. It was later replaced with a second, more common version.

However, and more surprisingly, only the first version was released on DVD, and the second version is now considered lost.
