Pokemon Legends: Arceus challenges the player to live up to one of the franchise’s most famous quotes, “Gotta catch ’em all,” as a part of the Survey Corps tasked with studying everything about the Pokemon in the Hisui region, modern-day Sinnoh.
Therefore, the player must be familiar with every Pokemon in the game. The player will also be given a personal quest to locate each Pokemon found in Hisui by the legendary Arceus.
This guide will discuss everything you need to know about Shellos in Pokemon Legends: Arceus!
Shellos
Shellos, the 82nd Pokemon in the Hisuian Pokedex in Pokemon Legends: Arceus, is a Water-type Sea Slug Pokemon with a body that resembles a slug, a pair of oval black eyes and white pupils that have a yellow outline, yellow lips, a mantle covering its body’s top half, a yellow on the edge of the mantle, and legs that are similar to slugs. Shellos has two forms: the West Sea Form and the East Sea Form.
Its West Sea Form has a white underside, a pink mantle with spikes on its back, and fleshy knobs on top of its head.
Its East Sea Form has a green underside, a blue mantle with flaps on its back that look like ceratas with yellow outlines, and a pair of tentacles with white tips on top of its head that extend away from its face.
According to its Pokedex entry, many Shellos can be found near seashores of warm waters. Also, Shellos are surprisingly friendly and will approach anyone it sees, but people should be careful not to get coated with their mucus.
Basic Information
Shellos is a Water-type Pokemon which means it is weak (super effective) to Electric-type and Grass-type moves and is resistant (not very effective) to Fire-type, Water-type, Ice-type, and Steel-type moves.
Its base stats are 76 HP, 48 Attack, 48 Defense, 57 Special Attack, 62 Special Defense, and 34 Speed, for a total of 325.
Shellos can be evolved to a Gastrodon once it reaches Level 30.
Springy Mushrooms, Hearty Grains, and Plump Beans are Shellos’ favorite foods. Like berries, these foods can be thrown at Shellos to feed or distract it so it can be caught or fought without the player being seen.
The player can get a Ball of Mud and a Pinap Berry when a Shellos is captured or defeated in the wild.
Location
To encounter a Shellos, the player can go to these locations:
In the Obsidian Fieldlands: on the shores south of Sandgem Flats and around Ramanas Island. The Shellos that are situated here are the West Sea Form.
In the Cobalt Coastlands: in Seagrass Haven and the islands on the northeastern part of Tranquility Cove. The Shellos that are situated here are the East Sea Form.
Shellos can be encountered in these locations at all times of the day and in every weather condition.
In addition to these locations, the Obsidian Fieldlands and the Cobalt Coastlands may contain a group of Shellos in Massive Mass Outbreaks.
Research Tasks
The following are the Research Tasks in Shellos’s Pokedex entry in Pokemon Legends: Arceus:
| Multiplier | Research Task | Objectives |
| x2 | Number caught | 1/3/6/12/25 |
| Number of small specimens you have caught | 1/2/3/4/5 | |
| Number you have caught without being spotted | 1/2/4/6/10 | |
| Number defeated | 1/2/4/10/15 | |
| Times you have seen it use Water Pulse | 1/3/6/12/25 | |
| Times you have given it food | 1/2/4/6/8 | |
| x2 | Number of different forms you have obtained | 2 |
| x2 | Number you have evolved | 1 |
A Pokemon’s Pokedex entry must get to Research Level 10 to be assessed as complete. Unless the Research Task objective has a multiplier of x2, in which case completing one of its objectives provides two Research Levels, a Pokemon’s Pokedex entry’s Research Level increases by one level when a Research Task objective is fulfilled.

The player will receive Research Points for completing Pokedex entries and Research Task objectives. If enough Research Points are earned, the player’s Star Rank in the Galaxy Team will increase.
To quickly complete Shellos’s Pokedex entry, the player can feed a Shellos food or berries four times, then catch four Shellos’s without being spotted. Doing all these will tick the first, second, and third objectives of the “Times you have given it food” Research Task to get to Research Level three, tick the first and second objective of the “Number caught” Research Task to get four Research Levels because of its x2 multiplier, and tick the first, second, and third objective of the “Number you have caught without being spotted” Research Task to get the last three Research Levels needed to complete its Pokedex entry.
Moves
The player has two options for teaching Shellos new moves: level Shellos up or go to the Training Grounds.
Leveling Up
As Shellos levels up, it can learn and master the following:
| Move | Type | Learn Level | Master Level | Power | Accuracy | PP |
| Mud-Slap | Ground-type | 1 | 9 | 30 | 100 | 20 |
| Tackle | Normal-type | 5 | 14 | 40 | 100 | 30 |
| Water Pulse | Water-type | 9 | 18 | 60 | – | 20 |
| Ancient Power | Rock-type | 15 | 25 | 60 | 100 | 15 |
| Mud Bomb | Ground-type | 21 | 31 | 65 | 85 | 15 |
| Earth Power | Ground-type | 29 | 40 | 80 | 100 | 10 |
| Recover | Normal-type | 37 | 48 | 0 | – | 10 |
| Hydro Pump | Water-type | 47 | 59 | 100 | 85 | 5 |
Training Grounds
Shellos can learn the following by speaking with Captain Zisu in the Jubilife Village Training Grounds (northeast corner of the village):
| Move | Type | Power | Accuracy | PP |
| Rest | Normal-type | 0 | – | 10 |
| Water Pulse | Water-type | 60 | – | 20 |
| Icy Wind | Ice-type | 60 | 95 | 20 |
| Earth Power | Ground-type | 80 | 100 | 10 |
| Ice Beam | Ice type | 80 | 100 | 10 |
Relevant Request
Shellos is involved in Request 45, called the “Shellos of the East and West” Request.
To unlock this request, the player must complete the following:
- Receive the ‘A New Mission’ mission, the ninth mission of the game where the player must go back to Commander Kamado and report the player’s success after quelling the Lady of the Ridge Liligant’s frenzy
- Complete the Inspiration from Hippopotas Request (Request 24) from Anthe at the Clothier in Jubilife Village.
To start this request, head to the Clothier in front of the player’s assigned quarters and talk to the merchant in the purple kimono named Anthe. She will inform the player that a Pokemon called Shellos would be the perfect inspiration for new clothing designs, as it has two different forms depending on where they live. She will then tell the player she’d be inspired to compare Shellos’ two forms. Anthe will then ask the player to show her the two different forms of Shellos.
To complete this request, the player must catch both forms of Shellos and show them to Anthe. Again, the Shellos (West Sea) can be found in Sandgem Flats and Ramanas Island in Obsidian Fieldland. The second form of Shellos, Shellos (East Sea), can be found in the northeast island of Tranquility Cove and Seagrass Haven in the Cobalt Coastlands. It is worth mentioning that these locations are islands, so the player would be required to unlock Basculegion as a rideable Pokemon to reach these areas.
Finishing the Request
After catching Shellos’ two forms, return to Anthe, still in the Clothier, and talk to her; on the prompt, select ‘About your request…’; on the next prompt, select the Shellos (West Sea), and on the next prompt select the Shellos (East Sea).
Anthe will then comment on how charming it is that the Shellos change their ways depending on where they live. She will also realize that the people of Jubilife Village have traveled far from where they used to live and that, like the Shellos, a change in the color of their clothing is all they need.
Finally, the “Shellos of the East and West” Request is completed, and Anthe has added new items to her lineup. The player can check the new clothing items after talking to her.
Shellos can be easier to find, capture, and use in battle with the help of this guide. Shellos can be a great companion to the player’s party in Pokemon Legends: Arceus, helping with missions, requests, and even the legendary Arceus’ goal for the player to catch ’em all!
