Instructional walkthrough

Accomplishment of the dex requirements

In order to move forward with the Mew quest, you need the seen data of all Kanto Pokémon excluding legendary Pokémon on your Pokédex. Spawns for all Pokémon can be found in their specific pages.

Mewtwo Seen Data

To aquire the proper seen data to continue the quest and to get the Old Sea Map, you have to battle Mewtwo in Cerulean Cave.

Old Sea Map

When all requirements have been met, speak to the Know it all Man inside the Celadon Office, in Celadon City. He will reward the Old Sea Map, which is needed in order to travel to Faraway Island.

Faraway Island

With the help of the Old Sea Map, it is possible to travel to Far Away Island with a Lapras located in the bay south of Pallet Town. The travel will only be successful when the interaction to Lapras is done at 12:00-13:00 Pokétime.

Once arrived, a small way follows to the second part of the island where Mew hides at a bush.

Faraway Island

An interaction with the bush will trigger the fight with Mew. Make sure you bring sufficient Pokéballs and your desired sync. After the fight is over, you can leave the island with the sailor located at the beach on Faraway Island.
