I remember nillipuss dropping 1-2 jum jum stalks about 33% of the time you killed him, on live server now i've killed him 14 times and seen 1 stalk.
Either I have really bad luck or his loot table is off a bit.

Forum posts detail 2 jum jum stalk drops as well as brownie parts nearly every kill, and other trash loots that I've never seen besides some runes.
