Exploring East Sea and West Sea Shellos in Pokémon GO

The game Pokémon GO features two distinct forms of the charming Sea Slug Pokémon: the East Sea Shellos and the West Sea Shellos. Players can evolve these aquatic creatures into their respective Gastrodon forms. Starting from April 3, 2025, at 10 AM local time through April 7, 2025, at 8 AM local time, the upcoming event known as Stunning Styles will provide trainers the opportunity to encounter these forms through one-star raids and as rewards from Research tasks.

Many players aim to catch Shellos to evolve them into Gastrodon, a highly regarded choice for PvP battles in both the Great League and Ultra League formats. In this article, we’ll outline how trainers can obtain both East Sea and West Sea Shellos and address the question of whether these Pokémon can be shiny.

Methods to Obtain East Sea and West Sea Shellos

Trainers can acquire East Sea and West Sea Shellos through a variety of methods:

• Wild Encounters
• Raid Battles
• Hatching Eggs
• Research Tasks
• Trading with Friends

Wild Encounters

Trainers can find East Sea Shellos in the wild, particularly in the eastern hemisphere of the game. Meanwhile, the West Sea Shellos can be encountered in the western hemisphere, alongside other Pokémon like Aqua Breed Paldean Tauros and Heatmor.

Raid Battles

Both East Sea and West Sea Shellos will be featured in one-star Raid Battles during the Stunning Styles event. As Water-type Pokémon, they are vulnerable to Electric- and Grass-type attacks, making them susceptible to damage from moves that gain a Same Type Attack Bonus (STAB).

It’s important to remember that each Shellos form can only be found in their respective hemispheres. Trainers hoping to catch shiny versions may find luck during these raid encounters.

Hatching Eggs

Both variations of Shellos might also be hatched from 7 km Eggs, which can be obtained by opening Gifts from friends within the game. This adds another layer of excitement to acquiring these Pokémon.

Research Tasks

Players can encounter East Sea and West Sea Shellos as rewards for completing specific Research tasks during the Stunning Styles event. Additionally, there is an opportunity to catch them through paid Timed Research, which is available for a fee of US $2.00 (or the equivalent in your local currency).

Trading with Friends

For players who may miss out on capturing either form of Shellos, reaching out to in-game friends for a trade can be a practical solution. The Pokémon trading system encourages community interaction and helps trainers fill their Pokédex.

Can East Sea and West Sea Shellos be shiny in Pokémon GO?

Yes, both East Sea and West Sea Shellos have shiny forms in Pokémon GO. During the Stunning Styles event, trainers will experience an increased shiny rate, offering a greater chance to encounter these vibrant variations.
