IL022: Abra and the Psychic Showdown

Synopsis
Continuing on their way to Saffron City, a mysterious girl appears in front of the group. They ask her for directions and start following her. She disappears and leads Ash to a cliff where he falls. He is saved by Bulbasaur and they see Saffron City. Just when they get into town, they are greeted by Team Rocket who trick them into going through the warp tile by telling them they had won a prize for being the millionth person in the city. Jessie and James get Pikachu, but the same little girl saves Pikachu and the group. They end up outside after the encounter. They find the Saffron gym, but are warned by a strange man not to go in. Ash goes in anyway to discover a strange training facility. He battles Sabrina who is two people, the evil trainer and a little innocent girl. Abra is sent out for Pikachu to battle. During the match it evolves into Kadabra and beats Pikachu. Ash loses and the group find themselves outside of a doll house. They see that they have been shrunken and just as the little girl was about to squash them with a ball, they are teleported outside of the gym by the mysterious man who previously warned them away from the gym. Ash learns from the man that he must get a ghost Pokémon from Lavender Town in order to possibly beat Sabrina, and so they continue on their way.

Trivia

 * During this episode, it is stated that Ghost-Type are strong against Psychic-type when, during Generation I (the time of this episode's airing), Psychic-types were actually immune to Ghost-type moves. Similarly, in the Generation II episode Psychic Sidekicks, it is said that Psychic-types are strong against Ghost-types, although the reverse was true by then (however, Gastly, Haunter, and Gengar's secondary Poison-type does make them weak to Psychic moves).
 * The book  Night in the Haunted Tower  is based on this episode.
