Scrooge takes the kids to Valhalla for a decennial wrestling tournament against Team Ragnarök, led by Jörmungandr, for the fate of the world. While Scrooge wins the first round against Strongbeard, he hurts his back, forcing Dewey to take his place. However, Dewey begins doubting himself and loses the second round when he fails to get the crowd on his side. Before the final round, Scrooge helps Dewey see that doing the right thing does not always mean getting everyone’s approval. Though Dewey is no match for Jörmungandr, his determination rallies the crowd to his side and convinces Strongbeard to lend him his magical beard, which increases Dewey’s strength and allows him to win the tournament.
