Island of the Giant Pokémon (Japanese: きょだいポケモンのしま！？ Island of Enormous Pokémon!?) is the 17th episode of Pokémon: Indigo League.
Being stranded on an island, the heroes and Team Rocket lost their Pokémon, who wander around the island. To make things worse, they encounter some gigantic Pokémon, who do not listen to them. How will the Pokémon return to their trainers and get off the island?
This episode takes place after Ash, his friends, and Team Rocket are attacked by a bunch of Gyarados. Ash, Misty, and Brock have been washed up onto an island and they realize that four of Ash's Pokémon, including Pikachu, have gone missing. On the other side of the island, Jessie and James find out that both of their Pokémon are missing along with Meowth. They find a phone booth and they try to call their boss, Giovanni, but realize they don't have enough money for a phone call.
On another part of the island, Pikachu finds Ash's missing Poké Balls and calls Bulbasaur, Charmander, and Squirtle out of their Poké Balls. They see a Slowpoke fishing with its tail by the sea. Pikachu and Charmander go ask it for help but get no reply while Bulbasaur and Squirtle sit on the beach.
While they are trying to find Ash and the others, they find Team Rocket's Pokémon, Ekans, Koffing, and Meowth. Meowth tells Ekans and Koffing to attack Ash's Pokémon, because they are their enemies, only they won't listen. They believe that there's no such thing as a bad Pokémon and the only reason they're bad is because their masters are bad.
Ekans and Koffing become worried when Bulbasaur suggests that they may have been abandoned by their trainers. Pikachu insists that Ash would never do that to them. The two groups of Pokémon decide to team up to try to find their trainers. Meowth gets tied up for what he did to Ash's Pokémon in the past. While the other Pokémon are eating, a giant Rhydon attacks them. They escape, accidentally leaving Meowth behind. Pikachu runs back and unties him so he can escape. Meowth ungratefully says, "I could have gotten out myself."
At the same time, Ash and his friends are attacked by a giant Zapdos. They manage to escape and they decide to rest for the night. Ash vows to find his Pokémon no matter what. Meanwhile, Jessie and James are chased by a huge Moltres. While they are escaping the Moltres, they run into a sign and fall unconscious.
The next day, Jessie and James go back to the phone booth and try to call the boss, but he hangs up when they recite their motto. So Jessie comes up with another idea: they follow the wire, hoping it will lead them to civilization. They see a Pikachu and decide to catch it, not realizing that its a giant Pikachu. Not too far away, Ash and his friends are hiding behind a rock from a giant Charizard. The Pokémon are still looking for Ash and Team Rocket. They come across a giant Blastoise and Squirtle asks it for directions. The Blastoise responds by attempting to blast the Pokémon with water. They see a giant Venusaur and Squirtle asks Bulbasaur to ask it for help but he is too scared.
Team Rocket, still following the wire, are running away from a Kabutops. They jump into a railway cart to get away. It starts moving towards, the Kabutops instead of away from it. It gets its foot caught in the wire and is pulled along by Team Rocket. Ash and his friends find the giant Pikachu and Team Rocket comes along quickly in the railway cart and Ash, Misty, and Brock jump into the cart. They all soon see their Pokémon being chased by the giant Charizard, Venasaur, and Blastoise. They grab their Pokémon to safety as the cart goes by. The track the cart is on goes into a big loop and the cable on the cart snapped and gives a full speed and sent flying into the air, crashes into the giant Zapdos, which turns out to be a robot. Soon all of the other giant Pokémon crash and are revaled to be robots too and the cart crashed into the water along with Ash and the others with them. A boat of tourists approach the island and a tour guide says that on the Island of Giant Pokémon, Pokémon are ten times their normal size. The guide looks over and sees all of the broken Pokémon robots. The island is an attraction, owned by Giovanni, who isn't happy that the park is wrecked.
Ash and his friends continue their journey and head to Porta Vista. The Slowpoke from earlier is still sitting on the rocks and it has a Shellder clamped to its tail and it evolves. The newly evolved Slowbro says its name happily.
