I am at the dungeon where Zooknock is

 

 

 

I can't get the green bar from him, I've talked to him already.

 

But when I use my gold bar on him "Nothing interesting happens."

 

 

 

I have in my invi:

 

 

 

Monkey dentures

 

M'amulet mould

 

Gold bar

 

Gnome Royal Seal

 

Monkey bones (from a monkey near karamja valcano)

 

Ball of wool

 

 

 

What's missing? Because he's not giving me a green bar =/

you have to use all three...gold bar, dentures, and amulet mold on him..right click on each and select use..then click on Zoonock. that should work..also make sure its a karamaja monkey bones/corpse u have otherwise you will have to leave and come back with the right monkey..hope this helps
