They are excited to explore the area and learn more about the local Pokémon. As they walk through the town, they notice a commotion and decide to investigate.

They find a group of townspeople gathered around a large stone structure, which is revealed to be a Keystone. The Keystone is said to have the power to evolve certain Pokémon, and the townspeople are concerned because it has started to crack and emit a strange energy. Ash and his friends learn that the Keystone is crucial for the local Pokémon and that if it breaks completely, it could cause chaos in the area.
