Poké Ball Peril (なんごくポケモンとＧＳボール The Southern Pokémon and the GS Ball) is the 3rd episode of Pokémon: Adventures on the Orange Islands season.
Ash and co. arrived to the Valencia Island. Ash notices it is quite hot and advises they could swim. Brock reminds him they need to take care of work first, but they or Misty know not where Ivy is located. They visit a Pokémon Center and Brock flirts, but gets his ear pulled by Misty. Ash asks for location of the lab and Nurse Joy gives them the directions. Following the path, they arrive to her house and are soon greeted by her assistants, who show them where she can be found.
As they walk, they encounter a Gyarados, but a woman. The woman jumps and grabs her lab coat, introducing herself as Professor Ivy. They come to her lab and see the Ball. Ivy tells Ash they tried to open it, but had no luck and due to its golden and silvery color, they named it as GS Ball. As Oak researches a Magikarp, Ash calls him and tells they made it to Ivy, showing him the GS Ball. Ivy greets Oak and they tell each other they have read each other's articles, so they shorten the conversation and Oak is told Ash will give him the Ball. Team Rocket, meanwhile, are unhappy the blimp is destroyed, but Jessie encourages Meowth and James that they need to repair the blimp to get Pikachu for the boss.
As the heroes wander, Ivy lets them know the area is the lab they are in. Misty smells flowers and a Vileplume emerges, but Ash notices it has different color of flower. Ivy's assistant comes with the food and the Pokémon appear. The heroes notice they have different color about them and are told due to the different climate the Pokémon look different. Ash and Misty scold Pikachu and Togepi for eating without allowance, but Ivy lets them have the food. Ivy sees Butterfree does not want to eat and Brock tastes the food and sees the problem. He makes an addition to the food, as Butterfree wants to eat tasty food. Ivy is embarrassed as Brock shows more knowledge than she does, but they go back to the house.
At the house, they see a lot of mess, so Brock cleans up everything and makes dinner. After the dinner, Ash and Misty sleep, while Brock goes to Ivy, giving her snack. Ivy thanks him, as she records Vileplume's movement. Suddenly, a Raticate appears and gets engulfed by the pollen Vileplume spread. Ivy rescues it (and gets engulfed as well) and go to the Center. Joy reminds Ivy she could have been hurt, but is glad Raticate is saved in time. Next day, Ash and Misty are about to go, but notice Brock is not around. They see him doing chores and Ivy believes he wants to stay. Brock confirms, as he has much to learn here and to do. Ash and Misty respect his decision and depart, although find a bit strange without him around.
Though Ash has the blimp tickets, he and Misty know the last one was a bad flight. However, they see the blimp is better, as Team Rocket, as hosts, push them into the blimp. Ash and Misty want to eat, but Team Rocket cage them. They see the other twerp is not around, so they taunt these two twerps are in love. Just as Team Rocket are going to get Pikachu, Jigglypuff appears and sings. Team Rocket abandon the blimp, and while they managed to get the parachutes, they fall down asleep. However, Ash and Misty are in the blimp, still asleep, as it drifts away.
