The next day, Rowan does chores with the rest of the household. After dinner, Rowan, Orly, and Raff go down to the beach to bring Fen dinner. Down on the beach are the remains of metal barrels that 19th-century hunters used to boil penguins to render their fat. Rowan tells the children that she wants to destroy the barrels. Rowan and the children work together to dismantle the barrels and use the scrap metal to build a giant penguin statue.

Later, Rowan goes to the tool shed to return the tools she used to make the statue. The shed door is open, and she sees Dom opening a trapdoor. After he leaves, she investigates. Under the trapdoor, she finds Hank’s cell phone and passport.
