“GALI: Sink or Swim”

Gali makes her way to the center of the islet and dives in a deep waterhole she finds there. Thanks to her Great Mask, the Kanohi Kaukau, Gali can breathe underwater, and eventually finds the source of the trouble. There is a gaping hole on the bottom through which ocean water is entering, until Gali pushes a massive rock over the breach, sealing it forever.
