1. Get the "Golden Bell"
* This is the main reason you go to the top! Talk to the old man inside the tower. He'll explain the legend of the Golden Bell and give it to you.
2. Use the Golden Bell
* The Golden Bell is essential for progressing the story. You'll need it to awaken the Legendary Beasts (Raikou, Entei, and Suicune).
3. Explore the Bell Tower
* The Bell Tower itself is a bit of a mystery. There are some interesting details, and if you're paying close attention, you might find some hints about the legend of the Golden Bell and the Legendary Beasts.
4. Train (If you have time)
* The Bell Tower is a great spot to train your Pokemon if you need to level them up. You can use the nearby trainers and wild Pokemon.
After getting the Golden Bell:
* You'll need to find the Legendary Beasts: They're scattered across the Johto region. You'll need to use the Golden Bell at specific locations to attract them.
* Use the Golden Bell in other places: You can use the Golden Bell in other places around Johto, but the game doesn't make this explicit. You'll need to experiment!
