In The Legend of Zelda series, a Rupoor is an item that steals your money.
How does it work within the confines of the game world? Does the money just vanish? Does it get eaten? The question is asking how, using physics, the rupoor deducts rupees from Link. What kind of magical force makes the rupees disappear?
Best Answer
In Four Swords, the first game in which Rupoors appeared (though called Black Rupees), collecting one resulted in Rupees being ejected from your wallet. The players could pick the scattered money back up, but this is still a decent explanation: Rupoors repel Rupees like opposite-polarity magnets. This doesn't fully explain why lost money cannot be recollected in later games, but it's not a stretch to say it got flung somewhere that it can't be picked back up again.
