Davenport and the others struggled to catch up to Vampire and his two monster accomplices, Medusa and Swamp Beast, and re-arrest them, but failed due to every monster's current size: one-inch-high. It ended up shrinking the entire mountain and blowing it all the way to Los Angeles, California. However, Vampire had a plot to shrink himself down so he could escape the prison. He, Big Ed ( The Monster), Wolfmon ( Werewolf), and Mummy were guards at the Monster Mountain prison within a mountain in Transylvania, Romania, which kept several monsters, including Tyrannosaurus Rex and Cyclops. Henry Davenport-the Invisible Man, is narrating an explanation of the events that had happened. As a result, the special was also believed not only to be a pilot, but the first and only episode of this short-lived series. The special first aired on ABC (the American Broadcasting Company) on Halloween of 1992, and it was supposedly going to be picked up for a series, but never managed to do so due to low ratings of the pilot. While the pre-production and post-production processes for the special are based in the United States, it was animated overseas by Fil-Cartoons, a defunct animation studio in Manila, Philippines. It was developed for television by David Ehrman, Glenn Leopold (who wrote the script), and Joe Morrison, and directed by Don Lusk. The special was produced by Hanna-Barbera Productions in Los Angeles, California, the studio behind the creation of many cartoon characters including former Metro-Goldwyn-Mayer animation directors William Hanna and Joseph Barbera's Tom and Jerry, Huckleberry Hound, Yogi Bear, The Flintstones, The Jetsons, Doug Wildey's Jonny Quest, and Joe Ruby and Ken Spears' Scooby-Doo. Monster in My Pocket: The Big Scream is an animated television special featuring several monsters from Matchbox's Monster in My Pocket toyline.
