Pokemon Legends: Arceus Ultimate Gastrodon Guide

As a member of the Survey Corps tasked with learning all that they are able about the Pokemon in the Hisui region, modern-day Sinnoh, the player is pushed to live up to one of the franchise’s most recognizable quotes, “Gotta catch ’em all,” in Pokemon Legends: Arceus. In addition, the legendary Arceus will assign the player a personal quest to find every Pokemon that can be discovered in Hisui.

This guide will discuss everything you need to know about Gastrodon in Pokemon Legends: Arceus!

Gastrodon

Gastrodon, the 83rd Pokemon in the Hisuian Pokedex, is a Water and Ground-type Sea Slug Pokemon that has a body that resembles a slug, a different color body depending on its form, a round head with three round, black eyes, and white pupils, a mantle covering its body’s top half, a yellow stripe running along the edge of the mantle, and three pairs of stubby legs. Gastrodon has two forms: the West Sea Form and the East Sea Form.

Gastrodon’s West Sea Form has a pink underside, a brown mantle with three pink markings on each side, a pair of large tentacles that curve upwards on both sides of its head, a pair of smaller and straighter tentacles on both sides of its neck, and two lumps on its back. 

Gastrodon’s East Sea Form has a blue underside, a green mantle with a pair of blue spots on each side, a pair of tentacles angled slightly upward on its head, a pair of yellow cerata on its back that resemble fins, and a curvy yellow line on its back and sides. 

Gastrodon, according to its Pokedex entry in the game, feeds on beach sand. Furthermore, a fierce battle ensues whenever a Gastrodon encounters another in a different form.

Basic Information

Gastrodon is a Water and Ground-type Pokemon that is weak (super effective) to Grass-type moves, resistant (not very effective) to Fire-type, Poison-type, Rock-type, and Steel-type moves, and immunity (no effect) to Electric-type moves.

Gastrodon’s base stats are 111 HP, 83 Attack, 68 Defense, 92 Special Attack, 82 Special Defense, and 39 Speed, for a total of 475.

Gastrodon can be evolved from a Shellos once it reaches Level 30.

Gastrodon enjoys Springy Mushrooms, Hearty Grains, and Plump Beans, which, like berries, can be thrown at it to feed or divert it, letting it be caught or battled without the player being spotted.

When a Gastrodon West Sea Form is caught or eliminated in the wild, it drops a Ball of Mud and a Pinap Berry, both of which the player will obtain. Gastrodon’s East Sea Form, on the other hand, will drop a Ball of Mud and a Nanab Berry.

Location

To encounter a Gastrodon, the player can go to these locations in Pokemon Legends: Arceus:

In the Obsidian Fieldlands: on the shores southwest of Sandgem Flats and around Ramanas Island. The Gastrodon can be found here in the West Sea Form.

In the Cobalt Coastlands: in Seagrass Haven. The Gastrodon can be found here in the East Sea Form.

The player can find a Gastrodon in these locations at all times of the day and in every weather condition.

It is important to note that one of the Gastrodons found on an island northwest of Seagrass Haven on the Cobalt Coastlands is a Level 61 Alpha Pokemon. This Alpha Gastrodon can also be found here at all times of the day and in every weather condition.

Aside from these areas, there is a possibility that the player can find a group of Gastrodons in Massive Mass Outbreaks in the Obsidian Fieldlands and the Cobalt Coastlands.

Research Tasks

The following are the Research Tasks in Gastrodon’s Pokedex entry in Pokemon Legends: Arceus:

A Pokemon’s Pokedex entry must reach Research Level 10 to be regarded as finished.  When a Research Task objective is completed, a Pokemon’s Pokedex entry’s Research Level improves by one level unless it has a multiplier of x2; fulfilling one of its objectives provides two Research Levels rather than one. Completing Pokedex entries and completing Research Task objectives will give the player Research Points, which will raise the player’s Star Rank in the Galaxy Team if earned in a sufficient number.

To quickly complete Gastrodon’s Pokedex entry, the player can catch four Gastrodons with at least two of them caught without being spotted and make sure that the player catches at least one West Sea Form and at least one East Sea Form.

Performing these will fulfill the first, second, and third objectives of the “Number Caught” Research Task will give six Research Levels thanks to its x2 multiplier, fulfill the first and second objective of the “Number caught without being spotted” Research Task to gain two Research Levels, and fulfill the only objective of the “Number of different forms you have obtained” Research Task, which has an x2 multiplier, to get the last two Research Levels needed to get to Research Level 10.
