He started by showing them how to climb a log wall. They were reluctant to try so Chuck blew his whistle at them. He demonstrated his first stage by jumping right over the log wall and back onto the top. The Blues did exactly what they were told but they did it faster than Chuck, who was jealous at their performance.
In the next stage, Chuck demonstrated it by jumping through tires, but he got stuck in one, and rushed back to the Blues. However, one of the Blues lit the obstacle course on fire, worrying Chuck. They performed the task much quicker than Chuck, and without getting stuck in the tires due to their small size. Again, Chuck was jealous of them and goes to the Slingshot, where the Blues had slept in.
They then challenged him into flinging himself blindfolded and with heavy objects such as an anchor attached to him. He started launching himself, but crashed into a cliff and got stuck up there. The Blues went back to sleep in the slingshot, unwilling to help Chuck, who attempted to get their attention unsuccessfully by struggling to get to his whistle with his beak.
In the credits, Chuck could still be heard crying for help to get him off the cliff.
