The Saturn Coin is one of the one hundred Constellation Coins that the player can collect in Endless Ocean: Blue World. It is engraved with an image of the ringed gas giant, the sixth from our Sun, and can be found in the Cortica River Upstream area’s Spirit Falls, inside of the bowl-like structure below the waterfall and sitting at the feet of the frog statue to the right of King Amaru’s Aqueduct.
