"What's going on in Henesys" warrior quest

Stan wants me to find a clue that apparently drops from monsters in HHG3 only, but I can't seem to find it after spending at least an hour here. Anyone know how to get it? :f6:

Orange Mushrooms dropped it for me after about 20minutes. It's there though.

I had the same problem. Took me a little over 1 hour and 30 minutes to get it.

They all seem to drop from the 'strange' form of the monster. Such as Strange Orange Mushroom or Strange Ribbon Pig. =/

lol, I got it on my first monster i killed, literaly
