Fearless Wilson

Brewster and Zack are putting up a retaining wall along the edge of the river. Meanwhile, at the Chug-a-sonic Speedtrack, Wilson struggles to master the speed booster wagon under Hanzo's guidance. When Brewster drops a cage into the river and tries to retrieve it, he overreaches and his crane topples into the water pulling Brewster with it. Zack and Jackman try to pull him out, but even two strong chuggers aren't enough to stop him from slipping further into the water. Wilson must overcome his issues with the speed booster and get to the river superfast to help his friend.
