I'm quite sure there is something appropriately already made, but I don't know how to search OpenGameArt for it.

For my current RPG project, I want to give the monsters home locations.  So each monster will "decorate" its home location - and I look for graphics suitable for such. That could be pelts, piles of straw, sorts of nests, or anything to make a sleeping place comfortable. If you remember Dungeon Keeper, you know what I'm looking for :D

If you know where or how to find such graphics, please give me a pointer :)

The game is isometric, but I surely can adapt other graphics too if they have about the right viewing angle.

Edit:

I've attached a screenshot with temporary lairs - the yellow ovals, which the imps are sitting on. I want something more dungeonal-stylish for those.
