Where to Find Inkay in Pokemon Scarlet and Violet
Inkay, the small squid Pokemon, returns in Pokemon Scarlet and Violet as part of the Indigo Disc DLC, along with its unique evolution method. This dark/psychic Pokemon originally appeared in Pokemon X and Y for the Nintendo 3DS and featured a special method of evolution that required the physical rotation of the handheld device. This method is similar for the Nintendo Switch in the Pokemon Scarlet and Violet Indigo Disc DLC, with a few additional caveats.
Inkay is found in the Coastal Biome section of the Terarium, which is the northeastern section of the new area in the Indigo Disc DLC. While they do appear pretty much anywhere in this area, the best places to look are the beaches or in the water itself.
How to Evolve Inkay into Malamar
To evolve Inkay into Malamar, Inkay will need to be at least level 30, but all of the ones found in the wild should be over level 50. From there, you will need to level up Inkay to get them to evolve, but there are a few special parameters. Inkay will need to level up from battle, not EXP candy. You can use candy to get Inkay close to leveling up, but the final bit of EXP needs to come from a battle against either a trainer or a wild Pokemon. Inkay does not need to do the battling though.
Most importantly, your Nintendo Switch needs to be in handheld form and held upside down when Inkay levels up. No external controllers can be powered on, only the Joy-Cons attached to the Nintendo Switch. EXP is given out rather quickly in Pokemon Scarlet and Violet, so the best thing to do is turn your Switch upside down as soon as you see the enemy Pokemon’s HP hit zero and keep it that way until Inkay starts to evolve into Malamar. If you miss your shot, you will need to level Inkay up again while repeating the method.
