i just got reminded of this and i thought if anyone knows flash games then it must be newgrounds right
...i don't even know if it was on newgrounds at any point but i guess this would help at least a little

This one part just stuck in my mind for so many years.
There was a man standing in an all-dirt field.
You had to dig out a corpse of an animal, I think it was a rabbit or a deer, and you had to stick your hand in there and dig out a key.
It just had a black screen and squelching sounds the entire time, and the only other thing onscreen was a text box at the top.
Literally all I remember aside from this was that Dance of the Sugarplum Fairy was playing over the entire game, aside from the black screen part.
