Halloween (and It's Equestria counterpart Nightmare Night) is just around the corner, so Ronald McDonald decided that it would be a swell idea to throw a massive Halloween celebration in Ronald McDonald Hell, complete with a massive party, haunted house, and trick-or-treating for the kiddies! He then looks for help setting up this massive celebration, and soon, everyone in RMDH pitches in to start up the event. However a Kentucky Fried Enemy is listening.
Ronald soon invites his best friend Discord, and then invites Princess Luna so she can dress up as Nightmare Moon for the party. He then sees if Vinyl Scratch and Octavia could provide music for the event as well. Finally, he gets his closest companions in on the celebration. They all (especially Sweetie Belle) get very excited for the event and go find Halloween costumes.
Soon, the big day arrives. Everyone in RMDH is dressed up for the big Halloween celebration, and the Kaiju add some atmosphere by roaring and doing scary stuff. Soon Discord and Luna (now dressed up as Nightmare Moon) arrive and the celebration can fully begin! During the party, Ronald tells the scary story of the ghost of Colonel Sanders, and everyone is getting scared of the tale. Suddenly, a ghostly figure arrives and it looks like the ghost of Colonel Sanders! This sends everyone in a panic.
However, the "ghost" is soon terrified by the apperance of "Nightmare Moon", and Ronald soon finds a projector that was controlled by the Colonel. His plans thwarted again, the Colonel leaves RMDH, and the Halloween celebration continues once more with swell activities like bobbing for apples. craploads of candy, a Luigi's Mansion-styled haunted house, and trick or treating for the kidies!
