I did 105 clears total to get my white lanner, kept my totem things to see how many I did exactly. I saw 3 whistles in around the first 40 runs. After the initial 3 whistles, I didn't see it drop again until the one I finally got on the 105th clear, over 50 clears to see 1 whistle... Some see it 7 times in like 20 runs. RNJesus is just not there for everyone xD
