Chapter 101 summary
Luffy panics when the lighthouse goes out but Nami assures the crew she can navigate toward Reverse Mountain on the Red Line. She shows the map and explains that strong currents from the four seas will carry the ship up the mountain's waterway into the Grand Line. The crew debates the plan until the Going Merry drifts into the Calm Belt, where massive Sea Kings surround them. A giant frog Sea King sneezes and blasts the ship back into the storm. Nami realizes the currents will indeed drive them up the mountain and warns that missing the waterway means crashing and sinking. As they near the entrance the rudder snaps and the ship heads for the rocks, but Luffy inflates into a balloon to bounce them safely into the waterway. The crew holds on as the Going Merry races upward through the clouds. At the summit the ship bursts into sunlight and begins its descent toward the Grand Line.
