While Pokemon Legends: Arceus doesn't have the richest Pokedex in the series so far, it still does feature plenty of Pokemon species to catch and evolve throughout the Hisui region. Hisui is divided into smaller regions or main areas, which players unlock by progressing through the story, and some of them include rare Pokemon that are worth getting as soon as possible. One of the new Hisuian Pokemon lines in Pokemon Legends: Arceus is that of Goomy, which features Hisuian Sliggoo and Goodra, and this quick guide explains how to get them very early.
