I tried to complete this step of the quest twice now. The following links both say you give the grayish liquid to froglok slave in East Cablis which kills it and a Froglok Goo will appear on your cursor. This is broken on Red99 please put a Floglok Goo in Iksar Warrior "Pimped" inventory so I can move to the next step of the quest.
