Spoiler warning: If you have not completed the relevant game(s), then the following details could spoil your experience.
Rupeeland (also called Rupee Paradise[1]) is a place seen in Freshly-Picked Tingle's Rosy Rupeeland. A strange old man, Uncle Rupee, promises a middle-aged man entry to this so-called paradise if he collects many Rupees. Later in the game, it is revealed that Rupeeland actually is a horrible land where freedom does not exist, and where everyone is Uncle Rupee's slave. Uncle Rupee will turn the land into Rupeeland once he gets enough Rupees. That's why he needed them from Tingle.
