Bug day was Oogie Boogie's original town holiday prior to his arrival at Halloween Town.
According to the 2005 GameBoy Advance title The Nightmare Before Christmas: The Pumpkin King, Bug Day was the traditional holiday of Oogie Boogie's realm until the people of the real world stopped caring for it, due to it being a more disturbing and frightening holiday than even Halloween. As the holiday was discarded by the real world, the Bug Day door was removed from the Hinterlands: However, before the Bug Day door vanished, Oogie Boogie found the entrance to Halloween Town. After an attempt to overtake Halloween Town and replace it with New Bug Day, Oogie Boogie was thwarted by Jack Skellington, who exiled Oogie Boogie and the spirit of Bug Day to Oogie's underground lair.
