I think a fallen corpse would be great. Could set it to decay or not in the setting.
If decay is on, have setting for how long it would take.
Could visually do it in steps, first few days no signs, days after that make it look decomposed, then finally leave a skeleton.
Decomposer could attract animals.
Skeletons could stay, would need a shovel to bury it, or maybe a hammer to get bones.
Could make a setting where for x days it's only lootable by the owner, then after that anyone could.
