Alex's Adventures With The Real Ghostbusters: The Halloween Door is a three-part halloween special by LionheartCaptain and Startanica.
Alex and the Ghostbusters are celebrating Halloween in New York. Joining them are Simba, Nala, Timon, Pumbaa, Tantor, Terk, King Julien, Mort, Maurice, Louis, Leo Lionheart and Benny the Beast. But an evil man named Dr. Crowley wants to get rid of Halloween and asks the Ghostbusters for their assistance. They turn down his request by having Slimer chase him out of the firehouse, but not before his assistant, Fairweather, makes off with one of their PKE meters.
They use the PKE meter to activate Crowley's Anti-Halloween machine, which vaporizes anything to do with Halloween (candy, costumes, jack-o-lanterns, etc.). As a result, Crowley opens the Halloween Door in the sky and unleashes hundreds of creatures from the Netherworld into the real world, including the most powerful of the demons, Boogaloo. According to Egon, an ancient deal was made by Celtic Priests and Druids 2000 years ago, in which Boogaloo and the other creatures would leave the Earth forever if people pay tribute to them every Halloween. The Ghostbusters, along with their allies, must work together to figure out a way to get Boogaloo and all of his minons back through the door and restore Halloween before midnight, or else the deal will be permanently broken and the creatures will remain on Earth forever.
Benny, Leo, Simba and Alex get slimed.Added by Benny J. RossThings go from bad to worse when some of the creatures break in Ghostbusters Headquarters and free the captured ghosts from their containment unit, including the ghosts of Freddy Krugger, Jason Voorhees, and four of the most dangerous and Diabolical Disney villains : Jafar, Maleficent, Scar and Mirage. The team of heroes uses up the last of their proton packs' energies and traps to recapture the six ghosts. With time running out, Benny, Leo, Egon and Winston attempt to repair Crowley's machine, which was destroyed by the creatures, but to no avail.
The night is ulitimately saved by a little girl named Emma, who stands at Boogaloo's feet and laughs without fear, telling that he's funny, and asks for a Halloween story. Everyone now realizes that the Halloween deal is still intact as long as children aren't afraid and will continue to celebrate Halloween. The "Big Chief" of Helloween, Dracula, shows up and reminds Boogaloo that taking over the world is something that they just don't do on Halloween.
After Boogaloo and all of his minons are sucked back into the Halloween Door, everything is restored back to it's original state, and the heroes even get the evening back. Regardless, Dr. Crowely has not learned his moral and vows to continue his plot to do away with Halloween. Xiro, Dagnino and Slimer, annoyed by Crowley's ignorance, scare him back to his mansion, then everyone celebrates their victory with a Disney Princess medley.
