Nearing Ecruteak City Ash and co. encounter an apple orchard and decide to have some apples. Little did they know that there were traps all over the orchard and Pikachu is caught. They soon encounter a young woman by the name of Charmaine, who set up the trap. Brock falls head over heals for her and encourages her to punish Pikachu, who doesn't take it very well. Ash proves Pikachu's innocence by comparing Pikachu's teeth to the bite-mark on the apple revealing that the bitemarks are smaller than Pikachu's mouth. If that were the case, who are the real apple thieves and how did they get here?
