Erm, Kuiper9000, I would like to know why spiders and mushrroms carry money around. I like your monster ideas as well, but the items part are kind of unrealistic. Of course that\'s my view, and my views are rather confused and unorganized...
Anyway, another idea:
Name: Winged Lulf
Physical Appearence: The winged Lulf looks like a wolf with wings. However, there are some major differences between the Lulf and the wolf. Those differences would be the wings, obviously, and the fact that the hind legs are replaced by three sharp talons. The Lulf also has smaller ears than a wolf. Similarities include the sense of smell, nose shape, fur, and front claws, as well as the social behavior. The wings are always as half as large as the length of hte body as well. The Lulf can fly up to a height of 5M+75 feet, where M equals the length of the Lulfs wings.
Attack Style: The Lulf is unpredictable, and are highly intellgent. Lulfs never hunt alone, rather, they hunt in packs of at least two. Packs of five are the most common. Lulfs will surround their quarry, and will attack with their front claws in order to slash and tear. The talons are to be used to pick up smaller quarry from the ground and in some cases, air. The fangs of a Lulf are formidable, and will be used alongside the claws.
The Lulf has a habit of warding off attacks with its wings. While it protects the main body, the wings are made of a thin leathery substance. When a wing is damaged severely enough, the Lulf will lose the ability to fly. However, the Lulf will attack here and there, as well as everywhere, and are fierce predators.
Like the wolf, the Lulf only attacks when hungry or needs provisions for its secret stocks. They shy away from creatures that carry things, but in some cases, will not attack certain creatures at all unless there is no choice but to do so. If a Lulf is seperated from its kind, then it is weakened severely and will die in a matter of days.
