Wild goats of southern Rhovanion

The fintónarki, or wild goats, are odd beasts found on the plains south of Mirkwood. They have several characteristics that set them apart from the other goats of Middle-earth. For one thing, they are sometimes found in mixed herds with the wild horses of the area, an arrangement found nowhere else. Second, they are almost untamable, although it is reported that Elves may have some success at this task (although Elves are generally uninterested in animal husbandry). Third, they are immune to all naturally occurring ingestible poisons and hence can live on almost anything that contains nourishment. Finally, these strange creatures have an unquenchable desire to be scratched on the head, between their long, dangerous horns.

It is rumored by various denizens of the Talath Harroch region (particularly those with small, naive children) that if one should do one of these hoofed hedonists the favor of scratching it in the proper spot, it will become ever loyal to the person who scratches it. This tale has caused numerous injuries to youngsters seeking an unusual pet.
