Feawin and I were at the local store the other day, and stumbled across their Halloween display. One item caught my eye immediately:
These are supposed to be sprinkled across a table for a kid's Halloween party, but I think that they will make great terrain bits. They are a bit big - the skull piece is just over 1" long, but for fantasy games they will be just fine for an ancient battlefield or graveyard of giants! 25 pieces in all - skulls, rib cages, hand-wrist-forearm, feet, and thigh bones. The store we bought these at (we grabbed two) is notorious for overpricing, so these should be available for much less money.
