Oh wow! So they die when they move out and their spirits lingers to the innocent visitors... indeed that's creepypasta material!![]()
I came up with a great one for my original town (now deleted) when my villagers in a certain part of town kept disappearing (actually moving out when I got lazy about the game). It had something to do with a creature that lived in Resetti's drain that would come at night and steal away the villagers - a bit like the Grendel of Beowulf fame.
