    Regular voices were provided by Dave Coulier, Frank Welker, Maurice LaMarche, Arsenio Hall, and Kath Soucie. Guest voices were James Avery and Donna Christie.

    The story features Ray Stantz, Slimer, Egon Spengler, Winston Zeddemore, Peter Venkman, and Janine Melnitz, alongside the fairy-tale manifestations: the Gingerbread House, Rumpelstiltskin, the White Rabbit and the Queen of Hearts' Card Soldiers, Little Bo Peep and her sheep, the Giant, and the Giant's son.

    Plot

    After Ray finishes reading a fairy tale to Slimer, he notices the book is two days overdue and tells Slimer it has to go back in the morning. Slimer wants to keep it. Meanwhile, Winston and Egon work late in the basement workroom on a new machine designed to turn ethereal entities into solid matter so they can be captured more easily. Winston, noticing Egon has started mixing up his tools, talks him into finishing the work the next day.

    Around two in the morning, an unhappy Slimer takes the book and looks for a place to hide it. After the refrigerator and a rug under the Rec Room both fail, he settles on the basement and tucks the book beneath Egon's new machine, accidentally flipping a switch on its underside. The machine hums to life and glows.

    The next morning Janine takes a call: an enchanted forest has appeared in Manhattan. The Ghostbusters find the Gingerbread House from "Hansel and Gretel," which Slimer starts eating before the house comes alive and tries to eat them. Proton streams destroy the house and the forest, but Egon cannot explain how it happened and takes a sample of the remains for analysis. On the way back to Ecto-1, the car is stolen by a red-skinned dwarf who insists they will never guess his name. Once Ray realizes it is Rumpelstiltskin, naming him makes him vanish. The team is then trampled by the White Rabbit and the Queen's Card Soldiers from "Alice in Wonderland."

    Back at the firehouse, Little Bo Peep and her sheep are leaving. Slimer realizes the manifestations are his fault, grabs the book from the machine, and returns it to the library. He claims to have fixed the problem, but a giant beanstalk then grows into the sky and giant-sized garbage rains down. Egon works out that the machine turned the stories into real things and says he can reverse the effect if he has exactly the same book. He and Ray go with Slimer to retrieve it while Winston and Peter take Ecto-2 up the beanstalk.

    Winston and Peter reach a castle on a cloud, where they are knocked down by a giant child with a squirt gun and brought to his gluttonous father, who prepares to eat them. Egon notices Ecto-2's emergency beacon through his Belt Gizmo and realizes time is short. He rewires the machine, has Ray place the book on top, and activates it, dematerializing the giants and the castle just before Winston and Peter are eaten. The beanstalk and garbage vanish as well, and the team flies safely home.

    That night Slimer wants another bedtime story. Ray, done with fairy tales, is handed a magazine with a centerfold; he wonders aloud why the picture cannot come to life. Egon, assuming it is a "girly magazine," asks whether Slimer is too young for that sort of thing, until Ray reveals it is a dessert magazine.

    Production

    The episode was recorded on February 27 and May 22, 1987, with Arsenio Hall's lines recorded on February 27.2

    Notes

    The episode draws on several well-known tales and rhymes: "The Frog Prince," which Ray is reading at the open; "Hansel and Gretel" (the Gingerbread House); "Rumpelstiltskin"; "Alice in Wonderland"; the "Little Bo Peep" nursery rhyme; and "Jack and the Beanstalk." When the Ghostbusters confront the dwarf, it takes them three guesses to land on his name, echoing the three days the protagonist has to guess it in the original story.

    Winston nicknames the Giant "Mikey," a reference to the boy from the 1972 Life cereal commercials, and Peter tries to win the Giant over by offering his baseball card collection and claiming to root for the Giants. This is the only time the Belt Gizmo is shown picking up a warning from Ecto-2's emergency beacon; in earlier episodes ("Mr. Sandman, Dream Me a Dream," "The Headless Motorcyclist," and "Baby Spookums") it had served only as a communication device. The closing centerfold gag makes this the second Season 3 episode built around a sexual innuendo, after "Baby Spookums."

    Episode order

    In both broadcast and DVD order, "Once Upon a Slime" follows "The Bogeyman Is Back" and precedes "The Two Faces of Slimer."
