After battling in the Pokémon League Tournament, Ash and his friends return to Pallet Town for a hero's welcome. Team Rocket, as usual, ruins the party with another bumbling attempt to steal Pikachu, but Charizard sends them blasting off again. Professor Oak makes a request for Ash, Brock and Misty to go on another journey to bring back a mysterious looking PokéBall for him. On their way, Ash is in for another surprise when his Pidgeotto evolves into a Pidgeot just in time to save the day! Then Ash releases Pidgeot to protect the other Pidgey and Pidgeotto from the Spearows and Fearow.
This episode was considered the first season finale of Indigo League.
