Ep 23. The Whistle Stop

Ash and his friends are on the way to Goldenrod City when they stop at a small town named Sunnytown. They soon find out that the town is famous for its Pokemon whistle, which is said to be the most powerful whistle in the world and can even control wild Pokemon. However, the whistle has been stolen from the town's famous musician, Benny, and the town is in chaos as wild Pokemon are running rampant.

Ash and his friends decide to help the town by finding the whistle. They talk to Benny, who tells them that the culprit is a Pokemon thief named Attila, who works for Team Rocket. Ash and his friends head to a nearby train station to catch a train to Attila's last known location.

On the train, they meet a girl named Casey, who is a big fan of the baseball-themed Pokemon, Electabuzz. Casey is on her way to a tournament in Goldenrod City and is excited to show off her skills. However, she soon discovers that the tournament has been canceled due to all the chaos caused by the stolen whistle.

Ash and his friends arrive at Attila's hideout and sneak in, but they are soon discovered. Attila and his partner Hun, who is also a Pokemon thief, send out their Pokemon to battle. Ash and his friends bravely fight back, and in the chaos, Benny's beloved Clefairy takes back the whistle from the villains.

After the battle, the town is safe again, and Benny throws a concert to celebrate. Casey realizes that the real victory was in helping the town, not winning a tournament, and decides to stay in Sunnytown to help out.

Ash and his friends continue on their journey to Goldenrod City, knowing that they made a difference in the lives of the people and Pokemon they met in Sunnytown.
