I wished that was the drop rate for me >_
I went through 7 hours of gruelling grinding, both with the BP black skeleton and the black skeleton in the hidden passage in 4-2.
I spent exactly 3 hours with the hidden passage one, at 50 seconds per run, that's over 200 tries, just for that skeleton.
The actual drop rate for me was 1 in 400 :P
