Jumpity Jim is a fictional demon created by author R. Chetwynd-Hayes in one of his short story collections entitled The Elemental (Fontana 1974).
The Jumpity Jim is described as a monster that was a horrific cross between a deformed monkey, and a monstrous spider with a deflated face and a body that is long and of an unnatural pink coloration.
The Jumpity Jim can leap with great speed and agility, from where it obtained its name, though it prefers to exist as a parasite via burrowing itself into the back of human victims, once latched onto a victim it will remain upon them until a suitable replacement is found.
The short story where it is encountered details the tragic story of one such replacement, a young servant girl who is lured by an evil lord to become the next victim of the Jumpity Jim, in order to save his wife who had become possessed earlier; at the end of the story however the Jumpity Jim instead possesses the body of an insane preacher, though it is implied it later possesses the servant girl regardless after an angry mob gathers and kills the preacher.
History[]
The Jumpity-Jim is described within the story as being an Elemental, though it acts more like a possessive spirit.
The incantation for summoning the monster can be found in the fictional book by Conrad Von Holstein entitled Unnatural Enmities And Their Disposal, from which the following excerpt is taken:
"The Primate Horrific or Jumpity Jim hath little intelligence, being but a form of low existence that doth demand life essence and warm blood. Once it hath been raised it will leap about with much speed and agility, and, if that which it needs be not at hand, will depart with a mighty explosion.
But should there be within the radius of twenty feet, a virgin, who hath the right essence, and should the flesh of her back, that which lies between the neck and the upper portion of the loins, be bare, then will it leap thereon, and will become as part of the poor wretch, as doth the legs and other members that did God in his bountiful goodness provide.
Once the abomination has mounted the steed, it can in no wise be removed, unless a like-virgin, cursed with the same essence, can be induced, or forced, to accept the loathsome burden."
There is nothing to be gained by summoning the Jumpity Jim as it does not imbue the victim with super strength, immortal beauty, or any other worthwhile augmentation other than a large hump positioned between ones shoulder blades.
Once the monster is taken from the nether-world it can never return, for it has taken on the flesh of a meat eater.
The only way for it to survive is to move from host to host for eternity and no earthly walls can hold a Jumpity Jim.
