The Water-type Shellos and its evolution, the Water/Ground-type Gastrodon, made its debut in Gen 4. Shellos and Gastrodon can be caught in two different forms: pink (West Sea) and blue (East Sea). Unlike its predecessor,Pokemon Sword/Shield,Pokemon ScarletandPokemonVioletallows its players to obtain both forms without needing to transfer fromPokemon HOME.
With over 50 Water-types inScarlet/Violet, it’s possible for trainers to completely miss the sea slug Pokemon. They’ll need to be caught in order to complete the Pokedex. Fortunately,Scarlet/Violetplayers will only need to catch one of Shellos' (and Gastrodon’s) forms to unlock their dex entry.

Where to Find West Sea Shellos and East Sea Shellos
As a Water/Ground-type, Shellos' habitats are located nearbodies of water, particularly beaches.Scarlet/Violetplayers can find both Shellos forms at the following areas:
SinceScarlet/Violetis open world, players can catch either one after departing from Naranja/Uva Academy. However, it’s recommended that Koraidon/Miraidon unlockthe high jump ability(which players can get by doing the Path of Legends storyline) since certain provinces may be harder to reach without it.
Shellos isn’t too difficult to catch, but players may want to have the right amount of badges to make the catching process a bit easier.
Players can useNet Ballswhen catching Shellos, since these have an increased chance of a successful capture if the Pokemon is a Water or Bug-type.
Alternatively, Shellos can be found in2-Star Tera Raids. A 2-Star Raid means Shellos will be atlevel 20. Since a Terastallized Pokemon may have a different Tera Typing,Scarlet/Violetplayers will just have to see what the Raid-Shellos Typing is and use a Pokemonthat’s super effective against it.
How to Evolve Shellos & How to Catch Gastrodon
Shellos will evolve into Gastrodon atlevel 30. Once it becomes Gastrodon, it gains the Ground-typing as well, making it Water/Ground-type. This makes it immune to Electric-type moves, but gains a x4 weakness to Grass-type moves instead.
Teach Gastrodon the Poison-type move Sludge Bomb (via TM 148) to counter (most) Grass-type Pokemon.

Gastrodonisn’t meant to be an Attackerand works better as a Defensive Pokemon. It can learn the move Recover to heal itself and has access to powerful moves such as Earth Power (Ground-type) and can even learn Ice-type moves such as Ice Beam through TMs. Although slow, it’s immunity to Electric-type moves means it can battle most Electric-type Pokemon that Water-types would struggle against.
Both the West and East Sea Gastrodon can be caught in 4 Star Tera Raids (level 45) with a small chance of having their Hidden Ability, Storm Drain.If Gastrodon has Storm Drain, then it can’t be damaged by Water-type moves and will instead have its Special Attack increased by one stage.
Gastrodon can also be caught in the wild at the following locations:
It should be noted that West and East Sea Shellos and Gastrodons donothave any stat differences. They also have access to the same TMs. This meansScarlet & Violetplayers should just catch Shellos/Gastrodon based on whichever look/color they prefer.
