Roz walks along the seabed for half a day until she is out of the poison tide dust cloud. She is amazed by the underwater landscape but sad that the polluted water is devoid of life. She thinks about how Crag, the turtle, once told her that the seabed was once above water. Soon, Roz sees fish, sea sponges, crabs, and snails—a sign of clean water.

Roz meets an angry sea turtle who tells her to turn around to avoid the poison tide. Roz explains that she is immune to the tide, and the turtle snaps back, “Well, aren’t you lucky? The rest of us are fighting for our lives, and you’re just going for a pleasant stroll!” (68). Roz says she will find the Ancient Shark and solve the poison tide. The turtle apologizes for being rude and explains that he just witnessed thousands of sea turtle eggs destroyed by the poison tide. This makes Roz sad, and she pledges to help all the sea turtles. The turtle says he will spread the word that someone is trying to help.
