Honey Swamp gets freaktacular footage for a haunting documentary when she and the ghouls accidentally wind up at the Moonlight Ghost Gorebilee in the swamps of New Goreleans.
Draculaura, Frankie, Clawdeen, and Cleo have been invited by Operetta and Honey to a party in the swamps of New Goreleans. As they travel by rowboat, Honey excitedly predicts that the footage she'll shoot that night will guarantee her best documentary yet. Operetta off-handedly comments that while the party will be a good one, it has to pale in comparison to the Moonlight Ghost Gorebilee. Honey concurs and explains to their guests that the gorebilee is a mythical centennial celebration supposed to take place in the bayous.
Draculaura, who is in charge of the map, interrupts the conversation to inform the group that they have arrived at 111 East Gator Ghoulevard. It is awfully quiet though, and a suspicious Clawdeen finds out that Draculaura has been reading the map upside down. There were supposed to get to 777 East Gator Ghoulevard, which is on the other side of the swamp. Upset, Draculaura knocks over the boat's lantern full of fireflies, which form an arrow pointed towards the dilapidated mansion uphill. Having no way to make it to the party in time anyway, the group decides to check it out.
Inside the mansion, all they find is a large dust-covered ballroom and an old gramophone. Draculaura apologizes to Honey for ruining her documentary, but Honey assures her that they can still hold their own party right here. Draculaura grabs onto the idea and pulls down a sheet covering the hall's central window to get some light inside. Moonlight streams into the room, which triggers the gramophone to play an elegant melody. Suddenly, dozens of ghosts appear in the ballroom, dancing to the music under the light of the moon. Honey realizes that they've stumbled onto the Moonlight Ghost Gorebilee and promptly starts filming for what will be an even better documentary than she had originally set out to make, while the rest of the group joins the party.
