On the way to Dawn's next contest, Ash and friends encounter a Magnezone in a forest. The Magnezone is enraged and is quickly heading for a nearby town, so Ash and the others try to stop the rampaging Pokémon before it makes it to the city.

While on the way to the next contest town, Gible falls in a river. Buizel saves it. This attracts the attention of a trainer, who wants to have a battle between Buizel and his Mr. Mime. Ash agrees. Mr. Mime proves to be too strong for Buizel though. Following this loss, Buizel is determined to get stronger and defeat Mr. Mime.
