Ep. 91: Ash and friends visit Pikachu Valley and face a boss battle after Team Rocket attacks

91

Ash, Kiawe, and Mimo find Pikachu Valley, a location housing a massive Pikachu population. Their caretaker, Pikala, is an enthusiastic fan who provides the group with Pikachu ears and tails, demanding they communicate using Pikaspeak by appending "pika" to every sentence. Although Ash's Pikachu initially appears popular among the females, Pikala explains this is merely standard greeting behavior. Frustrated by this conduct, the leader Pikachu challenges Ash's partner to a battle. Ash's Pikachu emerges victorious and subsequently prevents Team Rocket from capturing the entire group of Pokémon.
