In "Ghostbusters II," the main antagonist is Vigo the Carpathian, a powerful and malevolent spirit. Vigo was a 16th-century tyrant who sought to regain his physical form and dominate the world. He resides within a painting in the Manhattan Museum of Art and attempts to possess the newborn child of one of the Ghostbusters, Oscar, to achieve this goal.

In "Ghostbusters II," the pink slime, also known as "mood slime," was created using a combination of various materials, primarily a type of non-toxic, water-based paint mixed with additives to achieve the desired consistency and color. The slime was designed to visually represent the negative emotions of New Yorkers, reacting to feelings like anger and despair. The production team used practical effects and puppetry to animate the slime in scenes, enhancing its eerie and supernatural qualities.
