Superb post OP!
If people aren't wild about the "toes" how about "pots of gold" that are randomly dropped instead? Or if you're wanting to stick with a body part, maybe "wishbone" or something similar.
"Goblin Toe" is my wink to D2. ;) I had originally thought of Goblin Heads, though... but really, they could drop nearly anything: a tooth, a nail, a foot, a medallion, an eyeball... oh, the possibilities!
