Fangafa looks like a bare, enormous thorn bush with slithering, branch-like outgrowths attached to a lumpy root-body the size of an ox. Eight of the outgrowths are much sturdier than the rest, like the arms of an octopus but bark-covered and with thorn spikes where the suction cups would have been. At the far end of these longer arms are narrow cracks that, if opened, reveal huge cat-like eyeballs. And close to each of these eyes is a small, dark and
malicious brain.
A primordial being, roused for an unknown reason, killing many of the Urrbukktur tribe, causing them to flee from the Underworld.
It was later discovered that Fangafa was Xanatha's rival, and also after the Vile Water. Fangafa could not get though from her rift into the tomb to get the water, but was slowly trying to break in, captivated by the Vile Water's power. The party got into a fight with her in SY06. Tomb of Dying Dreams, Part II, but were force to flee.
