After a flood breachs the camp walls, he bravely tries to defend Echopaw, only to be gulped up by the giant wave along with her. Ravenpaw and the rest of the apprentices, along with the help of Cloudheart, save both of them. He is shown later that day serveying the damage around camp, and helping with the clean-up efforts.
- After events happen leading to the creation of the Renengade Squadron, Wolfpaw re-named Wolfheart, joins the Renengade Squadron, a ruthless and skilled elite force of 11 chosen cats.
- He is later crushed to death by Gaara.
