Rupees

--Taken from Zeldapedia for easy, at a glance information!--
"Rupees are the main units of currency in the Legend of Zelda series and are obtained primarily by defeating enemies, by cutting tall grass or bushes, or from Treasure Chests. They are most often used to purchase items from shops of any sort, but are also used for admission to certain mini-games.
Rupees are otherwise identical gems of various colors, each color marking a specific denomination. The association between colors and values varies somewhat from game to game, but the standard has Green Rupees being worth one Rupee, Blue Rupees worth five, Red Rupees worth 20, and Purple Rupees worth 50. Other less common colors include yellow (worth 10 in The Legend of Zelda: The Wind Waker and The Legend of Zelda: Twilight Princess), orange, silver, and gold (worth 100, 200, and 300, respectively, but different entries in the series switch which color corresponds to which amount). In The Legend of Zelda: Ocarina of Time, Silver Rupees found in certain dungeons that are used to open doors are worth only five Rupees. In some games, Big Green Rupees are worth 100 and Big Red Rupees are worth 200. In The Legend of Zelda: Four Swords, The Legend of Zelda: Phantom Hourglass, and The Legend of Zelda: Skyward Sword, Black Rupees (known as Rupoors) actually have negative value and will cause Link to lose Rupees. In Phantom Hourglass, a Big Rupoor causes Link to lose 50 Rupees, while a standard Rupoor causes Link to lose 10.

Uses Although Rupees are used most often to buy items in shops, occasionally they have other uses. In the original Legend of Zelda, one Rupee is used up every time Link fires from his Bow. In A Link to the Past, if a set amount of Rupees is thrown into a certain ‎Fairy Fountain, a fairy will appear and increase Link's carrying capacity for bombs or arrows, at the player's choice. In Ocarina of Time, collecting all the Silver Rupees in a particular dungeon room unlocks the locked doors. In the magic-absent Twilight Princess, Rupees are used to fuel the Magic Armor.
Rupees are important in every Zelda game within the series, but are central to the gameplay in the multiplayer The Legend of Zelda: Four Swords. As such, this game adds Black Rupees (appearing in later games as Rupoors), which causes Link's Rupees to scatter across the ground, and Rupee Shards, which, when collected, can add up to a Rupee of great value."

-In this campaign, Rupees (and Rupoor) take on a different role, becoming a rare currency that drops only from Zelda enemies. It is an incredibly rare currency and is very valuable!
