The trio attempts to cross a rope bridge, but the wind starts to rip the bridge apart. Brock falls into the river below, while Misty and Pikachu cling to Ash. Ash ultimately manages to pull them up, and the three make their way to the end of the bridge. They make their way down to the river and go looking for Brock. At once, Misty falls into a pit trap, not unlike those made by Team Rocket. Ash pulls her out, and they go on looking. As they walk along, Misty’s toe catches a rope, and they find themselves suspended in a net. They are found in this state by the Bulbasaur. Ash speculates that Brock has been washed to sea and shanghaied by pirates; moments later, Brock appears and frees them from the trap. Brock relays his river experience and the fact that he was rescued from the rapids by a girl. Brock takes them to a village and introduces them to a girl, named Melanie.
