After Karana builds her new house, she decides she needs sea elephant tusks to use as spearheads. At the beach, an old and young sea elephant fight to the death. The young one wins and kills the older one.
Once seagulls pick the bones clean, Karana takes the teeth and makes four spears.
Karana decides to start a fire to push the wild dogs out of the cave. Fourteen run out. Karana kills two of them with her arrows and hits the leader with two, but they just run off.
Karana finds the leader wounded. She takes it back to her house and cares for it. She doesn't know why.
Karana finds the dog, now named Rontu, fighting two of the dogs from the wild pack. After the fight Rontu goes back to the house with Karana.
