Sea Witch Kaula is a siren who can be found on the north-western shore of Whale's Maw.
She plays a part in the Head of the Family miniquest. Rosie directs you to her for information regarding the moving of moai statues in the past. She then tells you a sad story of the moai of Whale's Maw, in which their moai got curious and asked to be moved to the shoreline and drowned. The player has to revisit Rosie after to continue the miniquest.
During Jed Hunter, she helps Navigator Jemi control the Thalassus temporarily using a ritual involving two tortle shell bowls.
