Ghostbusters II

After the discovery of the River of Slime and the return of the Ghostbusters, experiments were conducted on samples of the Psychomagnotheric Slime. Egon Spengler and Ray to learned how to shift the slime to a positive charge and they developed Slime Blower equipment in an effort to weaponize it. On New Year's Eve 1989, the Slime Blowers were used on the inside of the Statue of Liberty by Ray and Winston to help animate it in conjunction with a Walkman and PA System playing a cover of Jackie Wilson's "Higher & Higher" song. Ray and Winston used their Slime Blowers on Janosz Poha upon returning to the Manhattan Museum of Art. Winston hosed Ray himself after he was possessed by Vigo. Once Vigo was exorcised, Winston directed the slime at him and the painting while Peter Venkman and Egon Spengler fired Proton Streams at him.

Ghostbusters: The Video Game

During the Shandor Incident of Thanksgiving 1991, a Mark II Slimer Blower attachment was affixed to the Experimental Proton Pack and thrower. The positively charged Psychomagnotheric Slime was green instead of the pinkish color of the original strain. The Mark II was also upgraded with a Slime Tether mode designed to capture entities without spending time weakening them or moving physical objects. For more information on the Mark II Slime Blower, please see the Plasm Distribution System (realistic version) article.

The Mark II Slime Blower's Slime Tether is replaced by the Slime Mine, which the player can charge. The longer the charge, the larger the mine.

During a summer visit to New Orleans, the Ghostbusters were heckled by an angry mob who didn't want them to trap their beloved Marie Laveau. Peter Venkman strapped on a Slime Blower and doused the crowd in positively charged pink slime. The mob was neutralized and the Ghostbusters drove on to meet with their clients. As Peter went it alone temporarily, he ran afoul of the Phantom Truck Driver. When the Proton Pack proved ineffective, Peter spotted a Slime Blower and got an idea. He fired at the truck but discovered it was on the Slime Tether setting. As a result, the Phantom Big Rig crashed and was wrecked.

A year later, Egon brought a Slime Blower with him to Roger's Apartment after Janine Melnitz began discharging Yellow Slime. The positively charged pink slime, however, had no effect on the yellow slime. During Halloween, a Slime Blower was brought along. Ray used it on the Ghost Fire Wall erected around Central Park at the Glen Span Arch on West Drive, in the North Woods section. He was able to dissipate a section large enough for the team to enter the park. Since Ray had the only blower, he was left behind to dissipate the entire fire wall after Stingy Jack trapped himself. The following spring, the Slime Blower was used to free the Hart Island Ghosts from Vigo's control. Michelangelo retrieved a Slime Blower from Ecto-1 and doused Chi-You in slime. However, it wasn't enough to exorcise him from Winston. Leonardo and Raphael completed the separation. Slime Blowers were handed out to 101 Cadets during the mission to neutralize the Manhattan network of Ley Lines long enough for the Ghostbusters to capture the Bronx Spook.

After the Dimensional Bleed incident, the Ghostbusters dealt with busy period of work. Ray doused a businesswoman in positively charged Psychomagnotheric Slime to prevent a forced possession by the H2 Ghost attacking her. The ghost attempted to flee but Peter and Winston trapped it. The woman attempted to buy some of the slime but Ray declined her offer. Ray utilized a Slime Blower to exorcise an Atlantean Priest Ghost in possession of Egon inside Penn Station.

  • Stephen Dane was inspired by military flamethrower backpacks when designing the Slime Blower.[1]
  • The Slime Blowers were 3-4 times as bulky as the Proton Pack props. It took 3-4 people to help get them on Ernie Hudson and Dan Aykroyd. The only practical part was the gun. It was a device with a spinner that sent out slime driven by compressed air. The tanks on the packs were empty. In reality, the blowers were attached to external tanks, 4-5 feet in height, that supplied the slime.[2]
  • In the November 27, 1988 and February 27, 1989 drafts:
    • On page 81, after the toaster is animated with Psychomagnotheric slime and dances to "Higher and Higher," Peter wants to sell it. Egon notes they are investigating practical applications and thinks the slime could be a useful tool against certain types of manifestations. Ray reveals they have a prototype for a pressure-forced, neutronically metered, fully portable delivery system and sums it up as a "slime-blower." Peter sarcastically asks him to keep it under 150 pounds.
  • In a deleted scene that took place right before the start of Chapter 13: Mood Slime, Ray tells Peter the name of the Slime Blower is a "basic prototype Slime-azooka BB-900."[3]
  • The pink slime does make an appearance in the "Realistic Versions" of the game in Multi-Player Modes, where it can be picked up as a power-up, and used to coat ghosts with positively charged slime in order to make them fight with regular ghosts.

Dan Aykroyd says: "The slimeblowers were three times as heavy and four times as bulky as the original packs. I think it took three or four guys to get us into them every time. These slimeblowers are going to every mother's nightmare if they ever go to the toy market, believe me--they were built to spew slime all over the walls. They were fun, though--and a beautiful practical effect. The only thing that worked on ours were the guns. The tanks were empty. The gun was actually a practical device with a spinner in it that sent the slime out, and it was driven by a lot of compressed air. Off camera were the real tanks that fed our lines. These tanks were huge--four or five feet high--and contained slime and air. So every time we blew slime on screen, we actually attached to these huge external tanks."
