- “Ah. The crescent moon has filled out to become a FULL moon... Thus, Crescent Moon Island shall now be known as...Full Moon Island.”
- —Captain T. Ode, Paper Mario: The Origami King
Full Moon Island, initially known as Crescent Moon Island, is one of 11 accessible islands in the Great Sea in Paper Mario: The Origami King. It is charted in territory F-3 on the Sea Chart with a shape of a circle (a crescent moon until the middle of the island is brought up). To bring up the central portion of the island, Mario must first fish up a Sidestepper at the fishing spot and defeat it to spawn a Magic Circle for the Earth Vellumental. Once the central portion surfaces, there is a stone Toad statue right in the middle of the island. Mario can examine the statue to see a diagram indicating that this now-circle-shaped island forms a baseball diamond layout with three other islands, Full Moon Island corresponding to the first base. The diagram also depicts a diamond-shaped island to be found midpoint between the other islands (corresponding to the pitcher's mound). There is a chest containing a Mushroom Handle in front of the statue. In the same chest, Mario finds a note from Luigi saying, "Hey, Bro! Got the key! Come find me on the mushroom-shaped island!" Beneath both the statue and the chest is a slab with an important message for progressing through the Great Sea: "To collect the three orbs, you must journey to Diamond Island."
