Furdip warps around the room at random, and aggroes people randomly during the fight. You need to have one person (usually the tank) clicking the fountain in the center of the area. to harvest something from the liquid. When Furdip 'takes a break' and emotes, you nail him with the clickable harvested item. You then proceed to lay the smack-down on him with everything in the book, and should be able to burn him down to nothing before he starts warping again.
