The Luferlang

"A dangerous fellow to meet up with. Very likely to attack without any provocation. Bites but once a year, but the bite is sure death.

In case of an attack, the victim should suddenly hold a large mirror up beside himself. The double image will so confuse the beast that he will rush off in disgust.

The biting season usually occurs on July 12. An orange-colored handkerchief conspicuously displayed will invariably afford full protection. Green clothing of any shade should be studiously avoided at this season, as it serves to arouse the animal further."

Appearance
"Certain unique features make it easy, however, to identify the animal. A dark blue stripe down the spine, a bushy, swivel-jointed tail set in the middle of the back (this appendage is most useful in keeping off the flies) and all four legs triple-jointed are what the traveler should look for. These legs make it possible for the Luferlang to run equally fast in all directions."

A horse like creature with a tough, almost rubbery body covered in various shades of short horselike fur.

The luferlang has sharp square teeth and a constantly grinning mouth.

Physiology
Luferlang are extremely tough, possessing almost rubbery bodies allowing them to squeeze and contort into small and tight spaces.

They have supernaturally fast reflexes (making their bite even harder to evade).

Abilities
The most freakish, and effective ability of the luferlang is the its fatal bite. Any being or creature bitten by the devil horse will die, including seemingly immortal creatures such as "demons". If the bite is seemingly non-fatal the victim bursts into hysterical laughter before their heart explodes.

Extremely fast, with the a keen climbing ability, they can also leap great and high distances. Though they only bite victims once a year their hooves are deadly.
