What does Peter do to try and make Cole angry?

Chapter 27

Peter begins to pester Cole by mudding up his sleeping bag, destroying some of Cole’s carvings, and doing other things to annoy him. Cole offers him a totem pole of his own to carve, and Peter reluctantly accepts it. Cole is particularly angered when Peter denies that Cole was attacked by an actual Spirit Bear and says it was probably just a black bear. At the end of the chapter, Peter carves back the bear that he had scratched off of Cole’s totem pole, and Cole is so impressed by Peter’s carving skills that he asks Peter to teach him how to carve better.

Chapter 28

In this final chapter, Peter first proposes that he and Cole go soak in the freezing pond alone together. On the way, Peter starts pushing Cole after an angry dialogue. Cole refuses to fight back, which only makes Peter attack him harder—punching, kicking, and scratching Cole until he falls to the ground. Cole doesn’t do one thing to fight back.
