Ancestral book of Halfling Culture

[Ybolla]

Been awhile since I did any Skilling up with my tailor, who is a Halfling, and I can't seem to find my Ancestral book. The quest to get the book involves turning in a Cat Skull Cap to Bill Whistletop. This item allegedly drops from a Pickclaw mindripper in Clan Runnyeye. I went there and killed every goblin in the zone several times over an hour or so and never once saw a mindripper. Does anyone know if this mob still exists? For that matter, does anyone know if Ancestral Book of Halfling Culture still exists? Am I wasting my time looking for quest items for this? I looked both here and on Allakhazam's and I've come up empty and a tad bit frustrated.
Thanks in advance,

The book should still exist.

Not sure what to tell ya about the drop though as I am not familiar with halfling cultural.

Sure enough.
I found the mindripper after camping and coming back the next day. Took my ranger (for the better tracking) and slaughtered for maybe 20min before the mindripper spawned. Found him in the room with Evil Eye prisoners.
