Cutting away at the paint on the ship's railings Tintin realizes that they are in fact the camouflaged gold. The chest contained the real railings, and was just a red herring. Haddock finally returns the gold to Tetaragua. The main square in the capital is renamed Paparanic Square, and Haddock receives Tetaragua's highest decoration, the Order of the Scarlet Cheetah.
