Just curious? I haven't seen 3, but I've seen the others and I wasn't sure if it actually followed a timeline or if it was totally random.

Do you really think this is the kind of series that follows any "timeline"? "Leprechaun In Space" is a gag that producers thought is amusing and went ahead with it. That is all there is to it.

As the next chapter, Trimark had originally wanted to put the Leprechaun aboard Apollo 13. “Trimark, we have a problem” — an idea that started as a joke poster for their Christmas party.
