N Osenia Islet

North Osenia Islet (referred to in-game as "N Osenia Islet") is a small island located north of Osenia and southwest of the Sea of Time. It is explored in Golden Sun: The Lost Age. If you have the Sand Psynergy found in Gaia Rock and the Red Handkerchief found in Southeast Angara Islet, you can get to a cow and give it the handkerchief so that it will give you the Milk, which you can then use in West Indra Islet.
