Continuing the journey to Ecruteak City, Ash and friends arrive in a town where a happy little Yanma is constantly going around and accidentally breaking every window in town with its Sonicboom attack. Yanma's trainer, Zachary, loves his Yanma and wishes that his Yanma would stop. However, Zachary's father tells him that he needs to release Yanma back into the wild. Zachary is confused on what to do, and Ash and friends are there to help him decide what to do.

Catching a sweet scent on the breeze, Ash and Pikachu follow their noses to a nearby apple orchard. As Misty and Brock follow, they warn him not to eat the apples that don't belong to them. No sooner is this said than Pikachu is caught red-handed with couple of cores! Once Ash proves Pikachu's innocence to the orchard owner, Ash, Misty, and Brock agree to help Charmaine find the real thieves.
