Tumak adjusts slowly to life with the Shell Tribe. He helps the children gather food by shaking fruit out of a tree and they teach him how to laugh. He tries to fish with Loana but grows frustrated, as spearfishing is not like land hunting. While he is fishing, an Allosaurus traps a child in a tree. Tumak uses a borrowed spear to kill the animal and save the child, but does not want to return the spear to its owner. Later that night, Tumak steals the spear and a hammer from their maker, and attacks him when he tries to reclaim them. The tribal leader, Loana's father, banishes Tumak.
