Following the completion of the Pokémon League, Ash is back home in Pallet Town. Professor Oak and Delia throw him a party which of course Team Rocket crashes, but Ash is able to send them off with the help of Charizard, who proceeds to wreck the party. Later that day Professor Oak asks Ash to run a errand for him. He wants Ash to go to the Orange Islands and pick up the GS Ball from Professor Ivy. He agrees and leaves soon after. Along the way they become trapped ina forest where the same flock of Spearow from the beginning of Ash's journey is still causing trouble, along with their newly evolved Fearow leader. Now they must figure out a way to get out of the forest before the Spearow manage to get to them.
