Eddy leads the friends on a mountain-climbing trip. His backpack is unusually big. He shows off his backpack that has everything they need. On their way to the top they face several problems. Eddy tries to solve each problem with the tools he brought in his all-purpose backpack, but they never seem to work out. Seeing his less prepared friends have more luck resolving the problems, Eddy becomes more and more depressed. Night falls, and Pororo goes to find firewood for the campfire.
