Puritan Ghost

Puritan Ghosts are immortal entities that originated from a CGI stop motion animated film, ParaNorman to real life Earth. Whne they were introduced to real life Earth, all Puritan Ghosts are harmless and they don't even try to scare people or haunt places, unlike in that movie, and neither commit witchcraftery. Puritan Ghosts are actually very peaceful entities that won't effect any living beings. Since they're immortal, they don't need to feed, drink, sleep, etc. Unlike in myths, they don't disappear/vanish completely in sunlight nor they stay the same place for the rest of their lives, so they won't be restricted to the place where they died.
