The Old Sea Map (Japanese: ふるびたかいず Old Sea Chart) is an event key item needed to access Faraway Island in Pokémon Emerald. It was distributed during the Pokémon Festa event in 2005 in Japan. Like other event tickets are the only way to get Deoxys, Lugia, and Ho-Oh, this event ticket will allow the player to catch Mew. Like the GS Ball, this event item never reached international players without the use of cheating.
If players show the Old Sea Chart to a man in Lilycove City, he will take them on his boat to Faraway Island. After entering the island and going into the forest area, the player will engage in a chase with Mew until cornering it and battling it at level 30.
