Jack has come to tell a not-so-scary story about how anything can happen on Halloween night.

Jack’s ghost dog, Zero, then flies off carrying everyone along on a trick-or-treating adventure, where four friends – Mickey, Minnie, Donald and Goofy – find themselves drawn into a mysterious haunted house. Their journey takes them from one room of the house to another, encountering dancing skeletons, waltzing ghosts and a whole series of troublemaking Disney villains. “Disney’s Not-So-Spooky Spectacular” promises to be the perfect Halloween treat!

The fireworks are just part of the Halloween fun. Several attractions across the park receive special enhancements just for the Halloween party! New this year, when you follow the treat trail into the Monster World at Monsters Inc. Laugh Floor, they’ll interact in all-new ways with the comic cast of monsters, as they learn about the curious Human World holiday we call Halloween.
The Halloween overlays for Pirates of the Caribbean, Mad Tea Party, and Space Mountain have also been announced to return for 2019.
