Classification: XX
The gnome is a common garden pest found throughout northern Europe and North America. It may reach a foot in height, with a disproportionately large head and hard, bony feet. The gnome can be expelled from the garden by swinging it in circles until dizzy and then dropping it over the garden wall. Alternatively a Jarvey may be used, though many wizards nowadays find this method of gnome-control too brutal.
Graphorn
M.O.M. Classification: XXXX
The Graphorn is found in mountainous European regions. Large and greyish purple with a humped back, the Graphorn has two very long, sharp horns, walks on large, four-thumbed feet, and has an extremely aggressive nature. Mountain trolls can occasionally be seen mounted on Graphorns, though the latter do not seem to take kindly to attempts to tame them and it is more common to see a troll covered in Graphorn scars. Powdered Graphorn horn is used in many potions, though it is immensely expensive owing to the difficulty in collecting it. Graphorn hide is even tougher than a dragon's and repels most spells.
Griffin
M.O.M. Classification: XXXX
The griffin originated in Greece and has the front legs and head of a giant eagle, but the body and hind legs of a lion. Like sphinxes (see below), griffins are often employed by wizards to guard treasure. Though griffins are fierce, a handful of skilled wizards have been known to befriend one. Griffins feed on raw meat.
Grindylow
M.O.M. Classification: XX
A horned, pale-green water demon, the Grindylow is found in lakes throughout Britain and Ireland. It feeds on small fish and is aggressive towards wizards and Muggles alike, though merpeople have been known to domesticate it. The Grindylow has very long fingers, which, though they exert a powerful grip, are easy to break.
Hippocampus
M.O.M. Classification: XXX
Originating in Greece, the hippocampus has the head and forequarters of a horse and the tail and hindquarters of a giant fish. Though the species is usually to be found in the Mediterranean, a superb blue roan specimen was caught by merpeople off the shores of Scotland in 1949 and subsequently domesticated by them. The hippocampus lays large, semi-transparent eggs through which the Tadfoal may be seen.
Hippogriff
M.O.M. Classification: XXX
The Hippogriff is native to Europe, though now found" worldwide. It has the head of a giant eagle and the body of a horse. It can be tamed, though this should be attempted only by experts. Eye contact should be maintained when approaching a Hippogriff. Bowing shows good intentions. If the Hippogriff returns the greeting, it is safe to draw closer.
The Hippogriff burrows for insects but will also eat birds and small mammals. Breeding Hippogriffs build nests upon the ground into which they will lay a single large and fragile egg, which hatches within twenty-four hours. The fledgling Hippogriff should be ready to fly within a week, though it will be a matter of months before it is able to accompany its parent on longer journeys.
Horklump
M.O.M. Classification: X
The Horklump comes from Scandinavia but is now widespread throughout northern Europe. It resembles a fleshy, pinkish mushroom covered in sparse, wiry black bristles. A prodigious breeder, the Horklump will cover an average garden in a matter of days. It spreads sinewy tentacles rather than roots into the ground to search for its preferred food of earthworms. The Horklump is a favourite delicacy of gnomes but otherwise has no discernible use.
Imp
M.O.M. Classification: XX
The imp is found only in Britain and Ireland. It is sometimes confused with the pixie. They are of similar height (between six and eight inches), though the imp cannot fly as the pixie can, nor is it as vividly coloured (the imp is usually dark brown to black). It does, however, have a similar slapstick sense of humour. Its preferred terrain is damp and marshy, and it is often found near river banks, where it will amuse itself by pushing and tripping the unwary. Imps eat small insects and have breeding habits much like the fairies, though imps do not spin cocoons; the young are hatched folly formed at around one inch in length.
Jarvey
M.O.M. Classification: XXX
The Jarvey is found in Britain, Ireland and North America. It resembles an overgrown ferret in most respects, except for the fact that it can talk. True conversation, however, is beyond the wit of the Jarvey, which tends to confine itself to short (and often rude) phrases in an almost constant stream. Jarveys live mostly below ground, where they pursue gnomes, though they will also eat moles, rats and voles.
Jobberknoll
M.O.M. Classification: XX
The Jobberknoll (northern Europe and America) is a tiny blue, speckled bird which eats small insects. It makes no sound until the moment of its death, at which point it lets out a long scream made up of every sound it has ever heard, regurgitated backwards. Jobberknoll feathers are used in Truth Serums and Memory Potions.
Kappa
M.O.M. Classification: XXXX
The Kappa is a Japanese water demon that inhabits shallow ponds and rivers. Often said to look like a monkey with fish scales instead of fur, it has a hollow in the top of its head in which it carries water.
The Kappa feeds on human blood but may be persuaded not to harm a person if it is thrown a cucumber with that person's name carved into it. In confrontation, a wizard should trick the Kappa into bowing — if it does so, the water in the hollow of its head will run out, depriving it of all its strength.
Kelpie
M.O.M. Classification: XXXX.
This British and Irish water demon can take various shapes, though it most often appears as a horse with bulrushes for a mane. Having lured the unwary on to its back, it will dive straight to the bottom of its river or lake and devour the rider, letting the entrails float to the surface. The correct means to overcome a kelpie is to get a bridle over its head with a Placement Charm, which renders it docile and unthreatening.
The worlds largest kelpie is found in Loch Ness, Scotland. Its favourite form is that of a sea serpent (see below). International Confederation of Wizard observers realised that they were not dealing with a true serpent when they saw it turn into an otter on the approach of a team of Muggle investigators and then transform back into a serpent when the coast was clear.
Knarl
M.O.M. Classification: XXX
The Knarl (northern Europe and America) is usually mistaken for a hedgehog by Muggles.
The two species are indeed indistinguishable except for one important behavioural difference: if food is left out in the garden for a hedgehog, it will accept and enjoy the gift; if food is offered to a Knarl, on the other hand, it will assume that the householder is attempting to lure it into a trap and will savage that householder's garden plants or garden ornaments. Many a Muggle child has been accused of vandalism when an offended Knarl was the real culprit.
kneazle
M.O.M. Classification: XXX
The Kneazle was originally bred in Britain, though it is now exported worldwide. A small cat-like creature with flecked, speckled or spotted fur, outsize ears and a tail like a lion's, the Kneazle is intelligent, independent and occasionally aggressive, though if it takes a liking to a witch or wizard, it makes an excellent pet. The Kneazle has an uncanny ability to detect unsavoury or suspicious characters and can be relied upon to guide its owner safely home if they are lost. Kneazles have up to eight kittens in a litter and can interbreed with cats. Licences are required for ownership as (like Crups and Fwoopers) Kneazles are sufficiently unusual in appearance to attract Muggle interest.
Leprechaun (sometimes known as Clauricorn)
M.O.M. Classification: XXX
More intelligent than the fairy and less malicious than the imp, the pixie or the Doxy, the leprechaun is nevertheless mischievous. Found only in Ireland, it achieves a height of up to six inches and is green in colour. It has been known to create crude clothing from leaves. Alone of the "little people", leprechauns can speak, though they have never requested reclassification as 'beings'. The leprechaun bears live young and lives mostly in forest and woodland areas, though it enjoys attracting Muggle attention and as a consequence features almost as heavily as the fairy in Muggle literature for children. Leprechauns produce a realistic gold-like substance that vanishes after a few hours, to their great amusement. Leprechauns eat leaves and, despite their reputation as pranksters, are not known ever to have done lasting damage to a human.
Lethifold (also known as Living Shroud)
M.O.M. Classification: XXXXX
The Lethifold is a mercifully rare creature found solely in tropical climates. It resembles a black cloak perhaps half an inch thick (thicker if it has recently killed and digested a victim) which glides along the ground at night. The earliest account we have of a Lethifold was written by the wizard Flavius Belby, who was fortunate enough to survive a Lethifold attack in 1782 while holidaying in Papua New Guinea.
Near one o'clock in the morning, as I began at last to feel drowsy, I heard a soft rustling close by. Believing it to be nothing more than the leaves of the tree outside, I turned over in bed, with my back to the window, and caught sight of what appeared to be a shapeless black shadow sliding underneath my bedroom door. I lay motionless, trying sleepily to divine what was causing such a shadow in a room lit only by moonlight. Undoubtedly my stillness led the Lethifold to believe that its potential victim was sleeping.
To my horror, the shadow began to creep up the bed, and I felt its slight weight upon me. It resembled nothing so much as a rippling black cape, the edges fluttering slightly as it slithered up the bed towards me. Paralysed with fear, I felt its clammy touch upon my chin before 1 sat bolt upright.
The thing attempted to smother me, sliding inexorably up my face, over my mouth and nostrils, but still I struggled, feeling it wrapping its coldness about me all the while. Unable to cry for assistance, I groped for my wand. Now dizzy as the thing sealed itself about my face, incapable of drawing breath, I concentrated with all my might upon the Stupefying Charm and then — as that failed to subdue the creature, though blasting a hole in my bedroom door — upon the Impediment Hex, which likewise availed me naught. Still struggling madly, I rolled sideways and fell heavily to the floor, now entirely wrapped in the Lethifold.
I knew that I was about to lose consciousness completely as I suffocated. Desperately, I mustered up my last reserve of energy. Pointing my wand away from myself into the deadly folds of the creature, summoning the memory of the day I had been voted President of the local Gobstones Club, I performed the Patronus Charm.
Almost at once I felt fresh air upon my face. I looked up to see that deathly shadow being thrown into the air upon the horns of my Patronus. It flew across the room and slithered swiftly out of sight.
As Belby so dramatically reveals, the Patronus is the only spell known to repel the Lethifold. Since it generally attacks the sleeping, though, its victims rarely have a chance to use any magic against it. Once its prey has been successfully suffocated, the Lethifold digests its food there and then in their bed. It then exits the house slightly thicker and fatter than before, leaving no trace of itself or its victim behind (The number of Lethifold victims is almost impossible to calculate since it leaves no clues to its presence behind it. Easier to calculate is the number of wizards who have, for their own unscrupulous purposes, pretended to have been killed by Lethifolds. The most recent instance of such duplicity occurred in 1973 when the wizard Janus Thickey vanished, leaving only a hastily written note on the bedside table reading 'oh no a Lethifold's got me I'm suffocating'. Convinced by the spotless and empty bed that such a creature had indeed killed Janus, his wife and children entered a period of strict mourning, which was rudely interrupted when Janus was discovered living five miles away with the landlady of the Green Dragon.).
Lobalug
M.O.M. Classification: XXX
The Lobalug is found at the bottom of the North Sea. It is a simple creature, ten inches long, comprising a rubbery spout and a venom sac. When threatened, the Lobalug contracts its venom sac, blasting the attacker with poison. Merpeople use the Lobalug as a weapon and wizards have been known to extract its poison for use in potions, though this practice is strictly controlled.
Mackled Malaclaw
M.O.M. Classification: XXX
The Malaclaw is a land-dwelling creature found mostly on rocky coastlines around Europe. Despite its passing resemblance to the lobster, it should on no account be eaten, as its flesh is unfit for human consumption and will result in a high fever and an unsightly greenish rash.
The Maladaw can reach a length of twelve inches and is light grey with deep-green spots. It eats small crustaceans and will attempt to tackle larger prey.
