The Black Slime Behemoth is a grotesque ghostly beast and an antagonist in the stylized version of Ghostbusters: The Video Game. It is a giant, cyclopic tentacled monster that comes from the Black Slime.


The Black Slime Behemoth is the boss in the Shandor's Island level of the game. It is a giant, cyclopic tentacled monster that resides in the giant black slime pool in the middle of the Main Orrey room. By equipping the P.K.E. Enhanced Goggles, the Ghostbusters can scan it for weak spots. There are three glowing nodes in its tentacles. Hit them all with Slime Mines and it is defeated. But beware! The Black Slime it spits at its prey is not only deadly, but it also spawns Black Slime Scuttlers. Dispatch them with Slime Mines.

In the end, the Ghostbusters defeated the creature.




  • In the Realistic version, the Black Slime Behemoth is replaced with a Sloar.
  • It is revealed that the creature is a Black Slime Monster.
