The Seafoam Islands (Japanese: 双子島 Twin Islands) are a pair of islands that are situated on Route 20. The two islands are shaped the same, as if they were twins.

Terminology

This place is called Seafoam Island on the Kanto map seen in Pokémon: Official Nintendo Player's Guide (page 3), Pokémon Gold and Silver: Official Nintendo Player's Guide (page 5), Pokémon Gold and Silver: Complete Pokédex (page 93), and Pokémon Crystal: Official Nintendo Player's Guide (page 5).

Geography

The caves beneath the islands are full of twists and turns and have five separate floors. To complete the trek through them, a series of puzzles which involve using Strength^RBYFRLGHGSS or Strong Push^PE to move boulders to block the flow of water, as the current is too fast to Surf^RBYFRLGHGSS or Sea Skim^PE across, need to be solved. Any attempt to Surf/Sea Skim on the currents will result to being sent back to where the current ends each time, and it is impossible to fight the currents. When the puzzle is solved, the boulders will stay in the water permanently.

The Seafoam Islands is roost of the Legendary Pokémon Articuno. It is located on the lowest floor of the caverns under the islands. It is also where Misty comes to train. In Generations II and IV, the Cinnabar Gym has been relocated here after the original Gym was destroyed by a volcanic eruption on Cinnabar Island.

Differences among generations

In Generations I, III, IV, and VII this is the home of Articuno.

In Generations II and IV, the destruction of Cinnabar Island causes Blaine to move his Gym to the Seafoam Islands.

In Pokémon HeartGold and SoulSilver, while Blaine's Gym is still located in the east cave, Articuno can be found here as it was in Generations I and III. As soon as the player walks into the east cave, there is a ladder that leads to an upper level where Blaine's Gym is located. There is also a set of stairs leading to a lower level in the islands just past the ladder. The Gym is much bigger than its Generation II counterpart as it sports a brand-new puzzle with junior Trainers. The interior of the island received a massive redesign as well. The cave section of Seafoam Islands uses the same music as Johto dungeons such as Ice Path, as opposed to the music used in Kanto dungeons. Also, unlike previous generations, there are three Trainers within the islands; two Boarders and one Skier.

In the anime

Seafoam Islands in the anime

Main series

In The Scheme Team, Agatha asked Scott if he had managed to find any strong Trainers in the Seafoam Islands. In Queen of the Serpentine!, Metallica Island is mentioned to be located past the Seafoam Islands; however, it is incorrectly referred to in the dub as Seafoam Island.

In Battling in the Freezing Raid!, Ash and Goh visited the Seafoam Islands to find an Articuno, which Goh needed to face in a Raid Battle to clear a Project Mew Trial Mission. Along the way, they encountered Horace and Gary, who joined them in the Raid Battle once Articuno was found. While they were unable to defeat Articuno, they fared well enough to pass the mission.

Seafoam Islands in Pokémon Origins

In the dub, the recurring location Seafoam Island (Japanese: ビンヌ Binnes) derives its name from the Seafoam Islands. However, this beach resort has no relation to the icy Seafoam Islands that appeared in the games.

Pokémon Origins

Red was briefly seen visiting the Seafoam Islands in File 4: Charizard, where he caught Articuno.

In the manga

Seafoam Islands in Pokémon Adventures

Pokémon Adventures

Red, Green & Blue arc

The Seafoam Islands first appeared in You Know... Articuno, where Red arrived there with Misty. He then traded his Krabby for her Gyarados, after which Misty left on her Starmie. Later, while walking on the island, Red and his Pokémon spotted Team Rocket members attempting to capture Articuno. Red fought against their Muk, but in the middle of the fight, his new Gyarados's past trauma of being experimented by Team Rocket caused it to go out of control. This gave Muk an opening to attack Red, until it was frozen by Articuno to save him. With Gyarados calming down as well, Red considered the battle won. However, unbeknownst to him, Articuno had spent so much energy to save him that Team Rocket succeeded in capturing it soon afterwards.

Yellow arc

In Extricated from Exeggutor, Yellow briefly stopped at Seafoam Islands while crossing the sea with Pika. During her brief stay, she encountered a wild Farfetch'd, which was having trouble finding its nest in a forest. Eventually it turned out that the "forest" was actually just a mass of migrating Exeggutor and Oddish. Yellow then called Professor Oak, who told her that the unnatural migration was likely a sign of the Pokémon sensing an upcoming disaster, foreshadowing the Elite Four's attack on the Kanto region.

Seafoam Islands in Pokémon Zensho

Pokémon Zensho

The Seafoam Islands appeared in Cinnabar Island. Satoshi first passed by them on his way to Cinnabar Island. While doing so, he released the Seel he had received from Misty. He also caught a sight of Articuno, but it flew off before he could catch it. He then also met Blaine, the Gym Leader of Cinnabar Island.

After defeating Blaine at the Cinnabar Gym, Satoshi agreed to help him catch Articuno. With the help of Satoshi's Jigglypuff's Sing, Blaine was able to catch the Legendary bird for himself.

Trivia

• In the Japanese versions of the Generation I games, Pokémon FireRed, LeafGreen, Let's Go, Pikachu!, and Let's Go, Eevee!, a Picnicker on Route 20 states that the Seafoam Islands used to be two islands, implying that they are currently considered a single island. However, in the English versions, the Picnicker instead states that the Seafoam Islands used to be a single island.
• In Pokémon Yellow, Krabby has increased encounter rates when walking on 1F, B2F, and B3F, while Kingler has increased encounter rates on B1F and B3F and has been made available on B2F and B4F. Both are also available and quite common when fishing on B3F and B4F. This is likely a reference to Ash's Kingler, which was caught as a Krabby.
