I'm trying to find the actual case with the slime's involvement in the Ghostbusters franchise.

To my original understanding, the slime was something Vigo the Carpathian made/used and was brewing it under the museum for his return. In the photographs taken of Vigo (as well as well as Janosz's encounters with Vigo that there apparently is slime flowing from the sides of the walls in his palace. Ray and Egon even believe there was a connection between them. Also after Vigo's defeat the slime around the building cracks up and flies off.

However according to some, the slime was a separate entity in itself that Vigo was just using. Meaning the slime was one problem, and Vigo another.

However according to a wiki article it was said (from the video game) that the slime was in fact Shandor's slime that he created on his island which flowed into sewers that Vigo ended up using for his power. However, Shandor's slime was a black color, whilst the slime in GB2 was pinkish-red.

So what's the deal? Was it Vigo's slime? A separate thing all together, or was it Shandor's slime?

Depends on if you consider the game canon.

If you do, as I do, then its Shandors slime. Its explicitly said. And Shandor had different colors of slime if I recall, so that explains that.

If you don't consider it canon, which I obviously didn't before the game, I considered the pink slime something that Vigo conjured up.

It'd be all fine and dandy aside from the photos Peter took that were analyzed along with the visions we see of him talking to Janosz, since we see it behind vigo flowing, as if it were showing it was his creation.

It's about the only thing from the videogame that I actively discount as being canon, due to how it significantly undermines Vigo as a villain, reducing him from “a very powerful magician, Doctor Venkman… and a genius in many ways” to little more than a lucky opportunist.

It would still flow behind him if Shandor put it into the sewers if Vigo was there to derive power from it.

Here, I have an idea for you, King.

Let's say Vigo did create some of the slime with his magic, but didn't get very far with it, almost like a limitation that he couldn't overcome for some reason*. It took Shandor's weird magic/science hybrid to create the vast rivers of the stuff we saw in GBII and the game.

(*Trying to overcome that limitation is probably what finally drove him insane.)

Of course, that's just a rough sketch. I invite you and other members to help me fix the holes and build upon it.

My 2 cents (even though it's probably not worth that much):

I do consider the game to be canon. Before everything went well with the actors and the game, Dan was saying that the game WAS GB3. So, that's where I still consider it and I don't have a problem with the different slimes coming from Shandor.

For discussion purposes though:
Personally, I always thought Vigo was weak compared to Gozer. Gozer was a demigod, whereas Vigo was “a very powerful magician” but still ultimately a man.

However, in either theory, Gozer didn't create the slime - either Vigo or Shandor did - both of who were just men. So really you can take your pick as to which you think would be more powerful and likely to create the slime.

GBII seems to imply that the slime is a natural occurrence, a byproduct of negative human emotion.

Vigo simply needed a large amount of negative energy in order to return, and the slime provided that.

Whether Vigo initially knew of the slime, or if he was somehow the cause of it, was never fully spelled out in the film.

To me, the imagery of Vigo and the slime together is of a more prophetic nature. Psychic imagery, a glance of things-to-come, not “yep, here's a picture of Vigo and that slime he was always messin with”.

I couldn't have said i better.

The slime and vigo were never connected in the movie. The slime sprouted many spirits(scolari bros, the titanic, PARK BENCHES!) Vigo was however the strongest presence.

So it doesn't undermime vigo, the only question would be where the slime originated. GB2 implyed that new york's negative energy,over time, spawned the slime. Whereas the game indicates that the slime was created by shandor.

Maybe they are related? Did shandor create the mood slime at first and new york's negative energy made it grow and develop?

I'm with Kingpin on this one.

One of the things GB2, for all of its flaws, did right is have an enemy that didn't have a blessed thing to do with Gozer. Similarly, it was a directive from J. Micheal Stracynski to the writers of The Real Ghostbusters to “forget about Gozer. He's history”. With all the mythology the property can (and has) used, both from real history, and made up , they knew there was no reason to have Gozer keep showing up every week.

But nowadays, everything has to be tied to Gozer. Gozer's father. Gozer's concubine. And probably the worst of them all, the Video Game retconning in a connection between Gozer and Vigo by saying the slime was really created by one of Gozer's worshippers–thus undoing the most major thing GB2 did right.

They need to quit this crap now before they end up like the Marvel UK comics and suddenly Gozer has a lumberjack cousin named Horg. (Yeah, I wish I was kidding about that…)
