There should be a new fight section in the battle part dedicated to the Ghost Town, complete with Ghost and Cursed Pokemon to fight, and a mention of the once-but-maybe-never-again popular video game town Lavender Town, the scariest place in Pokemon history. There should be a temporary map in the maps section dedicated to Lavender Town, complete with Ghost Pokemon like Unown and Litwicks. The map should stick around for about a week, then be taken down, and same gos for the Ghost fights.
