I have come on two separate cryptids to which the designation "White Thing" has been applied.
The first was noted from Happy Hollow Road in Alabama. It was white, the size of a human or taller and it uttered piercing screams. It is said to have been known locally for four generations.
The second was reported from Du Quoin, Illinois, in 1967. The witness on first glimpse thought it a dog, then saw it had an eyeless, human-like face and merely holes for ears. It had hands and a human-like feet and lacked a tail. Its mouth was a slit.
