Psychomagnotheric Slime (also known as Mood Slime and Psycho-Reactive Slime) is a powerful psycho-reactive plasm in Ghostbusters II and Ghostbusters: The Video Game that responds to human emotional states, both positive and negative, from which its reactions depends. It's main characteristic is an ability to open portals for ghosts to enter our realm, and it can also animate objects.

Primary Canon History
The origin of the Mood Slime is tied to a juvenile Sloar, held in Shandor Island, beneath the Hudson River. Before his death, Ivo Shandor and his Cult of Gozer had somehow lured the young Sloar from its home hell dimension and imprisoned it in our world within a Ghostworld pocket at the heart of Shandor's island mansion. Fueled by hatred, bile and anger the creature produced a steady stream of Black Slime.
Ivo Shandor, through experimentation and using equipment decades ahead of it's time, converted the Black Slime into what became known as the Mood Slime,  which was then pumped directly into New York's sewers and abandoned tunnels,  possibly as a means to help Gozer's crossing over. This act was later used by Vigo to his own advantage.
Ray Stantz and Egon Spengler conducted many tests on it to see how it reacts to different behavior. The tests included shouting, and insulting its weak electro-chemical bonds; as well as talking and singing to it, saying supportive nurturing things, and (in Egon's case, to the shock of the others) sleeping with it. Psychomagnotheric slime also has kinetic properties; it can cause a toaster to dance, or a bathtub to eat a baby as seen in Dana's bathroom. The slime also could be used by ghosts to enter the real world or boost their own power.
The slime concentrated in New York beneath the streets was under the control of a powerful spirit, Vigo, who used it to gather more power, form a shell of slime over the museum, and even used the slime to try to abduct Oscar. As the slime was building up in under the city it fed and grew in the old pneumatic transit lines due to the hostility and general negative emotions of the average New Yorker. Direct contact with this slime had the effect of filling a person with the negative emotions that it stores. Slime can also be positively charged. In this state, it can be used to move large monuments, small toasters, or even rid someone of a possession. The Ghostbusters used it in their Slime Blowers to animate the Statue of Liberty. Under Vigo's influence, negatively charged slime could even become aggressive enough to attack a person (as seen in a scene where Ray takes samples of it).
Ghostbusters: The Video Game
By 1991, Egon has further refined the substance into a more useful tool. Using his knowledge of spores, molds and fungus, Egon had developed an energetic, self replicating growth medium that can in theory provide an endless supply of positively charged slime and allowed for the Mark II Slime Blower to consist of only a small reservoir that can be attached to the standard Proton Pack. This is referred to as the Plasm Distribution System.
The primary reason for developing this medium is as a counter agent for the caustic Black Slime, a super-saturated negatively charged form of Ectoplasm that can create portals across the 4th and 5th dimensions into the Ghostworld. As a side effect, the pigment of the slime has changed from it's original pink into a dark green and although most of it's "emotive", "portal-opening" and "animating" properties have been reduced, care still needs to be taken while using the slime around loud punk, heavy metal and hip-hop music.
According to Tobin's Spirit Guide
- Category: None
- Abilities: Melee Attack, Black Slime Spit, Black Slime Coating
The standard response by most people to paranormal entities is often fright. I've seen some reactions to ectoplasm that run counter to this standard expectation. Some people, in fact, react angrily or become elated while others grow morose. I've isolated such incidents and can conclude that the ectoplasm residue in these cases is a subclass that seems to resonate and reciprocate human emotions.
Mood slime. With our recent breakthroughs in psychomagnatheric ectoplasm technology, we can align the valences of the substance to elicit a finely tuned range of emotions upon contact with a human target.
Don't get it on you...unless you're in a good mood.
The art page can be found in Shandor's Island, during the "Through the Good Slimes..." section. It is hidden inside a locker in the room Peter is being held in.
- Comes in various hues from blue, green, yellow, and pink. The Ghostbusters managed to re-work a pink strain into a more useful, but less powerful, positively-charged version. They later adopted a green strain a few years later.
- Could be charged by positive or negative energy, which drastically changes its behavior.
- Able to animate inanimate objects, like toasters, fur coats and even the Statue of Liberty. These objects could behave either hostile or benign, depending on the charge.
- Negatively charged mood slime can be used to create rifts for ghosts to cross dimensions or to boost and extend their own power or even as a weapon itself, as demonstrated by Vigo.
- In Ghostbusters II, when Egon Spengler and Ray Stanz scanned 1st Avenue where Dana Barrett's carriage was taken by the pink slime, it registered 1,118 on the P.K.E. Meter and 2.5 GeV on the Giga Meter.
- In its positive state, mood slime can drive out a possession as well as greatly weaken or even harm a powerful entity.
Psychomagnotheric Slime was used as a means to stop negatively charged objects, people, and ghosts as it neutralizes the negative energy and makes whatever it gets on to be inert. It was used in the Slime Blower in Ghostbusters II and in the updated Proton Pack in both versions of Ghostbusters: The Video Game.
No matter the charge, positive or negative, it can animate inanimate objects, stores and amplifies emotional energy and reflect it back at the physical environment, affects disposition with proximity or contact, and can facilitate possession or exorcism.

The Real Ghostbusters
After the battle with Vigo the Carpathian, the Ghostbusters collected the Psycho-Reactive slime.   Experiments proved it responded to a person's thoughts and emotions.  It could also grant a person limited ghostly powers such as flight.   Egon never could understand how it worked completely, though.
The next year, the Ghostbusters utilized the last of the slime in order to rescue Janine Melnitz and Louis Tully on Janine's birthday from Poso. They recruited Poso's former associate Shifter to aid them. However, Shifter stated he could only smuggle one of the Ghostbusters into Ghost Town, Poso's base of operations. Peter Venkman was volunteered and covered in the slime, currently in a yellow hue. After the rescue mission was a success, it became apparent the slime grew fond of Peter.  When Peter lost his temper, the slime changed its hue to red and skipped away with him in tow. They didn't get it off until Peter calmed down.

Over the course of the 20th century, the good will generated by amusement parks on Coney Island were absorbed by a pool of Psychomagnotheric Slime below in the sewers.  During the Ghostbusters' trial in 1989, a Officer Mallory decided to keep some of the confiscated Psychomagnotheric Slime for himself as a way to save money on ooze refills for his son's pirate reptile toys. Winston Zeddemore noticed him and his partner looking at the slime outside the court room. Winston tried to warn them the slime was dangerous but they snapped at him. The slime and negative emotions gave way to the manifestation of Mama Scoleri. Winston went outside to Ecto-1, found a Trap, and captured her. While Lou Kamaka modeled during a photo shoot, the photographer's rant triggered a nearby cache of Psychomagnotheric Slime. Lou punched the ghost.  The Ghostbusters concluded Psychomagnotheric Slime was the byproduct of the high amount of P.K.E. always present in a metropolitan area like New York City. They made a supposition that positivity from tourism and the victories of professional sports teams are what kept the city's negatively charged Psychomagnotheric Slime at bay over time. 
Years later, for a trip across the United States of America, the Ghostbusters took along several equipment including Slime Blowers. While in New Orleans, Peter doused an angry mob in positively charged pink slime so the Ghostbusters could move onto meet with their client. Peter later used a Slime Blower set on Slime Tether mode to neutralize the Phantom Big Rig. A year later, Egon attempted to neutralize Yellow Slime covering Janine Melnitz but the positively charged pink slime dissolved on contact and had no effect whosoever. During Halloween blasted a section of the Ghost Fire Wall around Central Park with positively charged pink slime. The slime successfully dissipated enough of the wall for the Ghostbusters to venture forward into the park. Ray was later tasked with dissipating the rest of the wall. The positively charged pink slime was also used for a Miniature Slime Blower Egon used against a projection of Santa Muerte.
After Tiamat trapped Dana in her apartment, she observed one of the brick wall obstructions seething with Psychomagnotheric Slime. Dana refused to wilt and kicked the brick wall away and tried to escape. The positively charged slime proved effective on liberating the Hart Island Ghosts from Vigo's control. After Winston Zeddemore sprayed them, they immediately swarmed Vigo. During an investigation at the St. Augustine Lighthouse on August 29, a liter of positively-charged Psychomagnotheric slime was brought along. The Ghostbusters later discovered a cursed statue at the nearby St. Augustine Alligator Farm Zoological Park. After the statue was neutralized in positively-charged Psychomagnotheric Slime, they were able to trap the Ghost Alligators. P.K.E. levels stabilized and the benign resident ghosts returned to their standard manifestations. On September 14, the Ghostbusters used negatively charged Psychomagnotheric Slime on Hedylogos. Hedylogos suffered visible pain, which disrupted its influence and weakened its P.K.E. reading significantly, which allowed them to trap it.
Michelangelo was curious about the Miniature Slime Blower so Peter explained it was concentrated good vibes to counter the negative energy of a direct possession.  Michelangelo was able to weaken Chi-You's possession of Winston with a stream of slime from a Slime Blower. Leonardo then zapped Winston with a modified Arm Mounted Proton Pack and fully exorcised Chi-You.
An even more compact mobile device was invented, the Slime Spritzer. They were utilized in the Louvre Museum. However, after the slime made contact with the Animated Louvre Art, the David, the Venus de Milo, the Mona Lisa and the Code of Hammurabi, the priceless works of art disintegrated. After the Ghostbusters secured the Rauoskinna, Peter sprayed positively charged Psychomagnotheric Slime on the cover in order to sever its connection with the ghost of Gottskalk Nikulausson. The use of positively charged Psychomagnotheric Slime in a highly negative environment has a caustic effect on corporeal entities. Ray was able to verify this by using his Slime Blower while the Ghostbusters were stuck in Hell. He slimed several of Hell's Demons. They screeched in pain as the slime melted parts of skin off their wings and bodies. Studies with Jenny Moran confirmed Corporeal Class 4 manifestations tend to be the most affected by exposure to Psychomagnotheric Slime. When exposed to enough of it, the ghost will revert to a more typical ghost form and thus, become easier to shoot and trap.  The Coney Island pool gave the ghost of recently deceased Jonas Schultz the power to return Luna Park as it was before a fire burned it down in 1944. Egon and Ray tried to neutralize the slime with negative emotions. Egon urinated into the pool and Ray used a Proton Grenade. They underestimated the reaction to the assault and the slime flowed to the surface, raining down all over Coney's communities. The mostly neutralized slime animated some playground equipment and it ran off.  A week later, the EPA decided to fine the Ghostbusters for willingly introducing a toxic element to a residential area as well as the Paranormal Contracts Oversight Commission for not being able to keep them in check.
Nearly all of the Ghostbusters 101 Cadets were duly deputized and taken to three points in Manhattan as part of the multi-part plan to capture the Bronx Spook and separate the two merged dimensions. Ray Stantz oversaw the team at Washington Square Arch, Erin Gilbert oversaw another, and Patty Tolan oversaw the last outside Central Park. They instructed the cadets to use their maps and Ecto Goggles the locate the Ley Lines then use their equipment to neutralize them with positively charged Psychomagnotheric Slime recently harvested from Coney Island. It worked and ambient psychokinetic energy levels dropped. With the ghost's power source cut off, it was pulled from between dimensions with the Ultimate Mobile Trap and captured. Ray and Raphael were at an impasse with trying to liberate the latter's body from a possessing Gjenganger. Raphael bemoaned being stuck in Ray's body forever. Ray told him he was so negative then got an idea. He instructed Raphael to use his Slime Spritzer and spray both his and Raphael's body at the same time. Ray gambled the slime would interact with Raphael the same way it would with a possessor since he was so angry. It worked and Raphael was ejected from Ray's body back into his own.
A field team of Ghostbusters from various dimensions went to Central Park of 00-D in search of the Headless Horseman. During the battle, Ray asked Erin Gilbert to widen her Proton Stream there threw out his vial of Psychomagnotheric Slime at it. The vial exploded and the ectoplasm spilled all over the Horseman and its horse. The "skin" began to peel off the horse as the slime reacted and the Horseman was thrown off. Samuel Hazer called out to Peter Venkman of Dimension 68-R but the Horseman was still in possession of him and lunged. A canister of Psychomagnotheric Slime inside the vehicle form of Ectotron. It was discovered during the fight with Kremzeek at the Grosbeak Generating Station. Winston suggested using it but Ray decided to keep it in reserve. Winston implored the others to think of a solution for saving the possessed Ectotron and stated he wasn't blowing anyone up. Peter eventually pointed to the canister of Psychomagnotheric Slime that Ectotron gave Ray earlier. Egon pointed out a small canister of it wouldn't be effective applied topically to the surface of such a large metal form. Ray countered they got the Statue of Liberty moving with it. Winston pointed out they used gallons of the ectoplasm for that. Egon believed they had to disperse it inside Ectotron. Peter voted himself out of trying to find his gas cap. Ray suggested force feeding it. Winston pointed out he was 20 feet tall. Egon noted they had one Trap left and it wasn't enough to force spectral expulsion. Peter elected to use the ectoplasm and yelled at Optimus to try to get Ectotron on his back. Megatron lifted Ectotron's right foot to stomp and stated there was no "try," was only success or failure, and the rest was meaningless struggle. Optimus caught Ectotron's foot and flipped him. Optimus disagreed and believed struggling was how success was learned. Peter was amused pop psychology made it into space. Ray instructed Optimus to hold Ectotron down. Optimus suggested he hurry as Ectotron seemed stronger. Ray joked he was fighting for two then climbed atop Ectotron's chest and poured the Psychomagnotheric Slime down his mouth. Megatron was ejected in a stream of Energon. Ectotron noted he shouldn't be physically capable of vomiting so he was not all right. Egon checked his P.K.E. Meter and alerted everyone of Megatron's re-manifestation.

Ramis admitted he had several ways to dramatize the latter.

- The negative emotions materializing as slime was a late addition to the movie.
- Back in 1984, Egon and Ray had a theory that human emotions could affect the physical environment.
- Colossal Pictures did a shot involving the Psychomagnotheric Slime rising through 40 feet of New York sediment-through layers of broken pipes, antiques, and the like then bubble through the cracks of a sidewalk. A set was built upside down and the slime was poured down then the crew flipped the shot. It ran for 20 seconds.
