Chudley

Chudley is the founder and proprietor of "Chudley’s Fine Goods and Fancy Trinkets Emporium," a high-class store in Hyrule Castle Town that charges incredibly large amounts of Rupees for items (2000 Rupees for a bundle of 10 arrows, 3000 Rupees for Red Potions, etc.).

Biography
Chudley is very snobbish, and won't even let anyone into his store unless they've had their shoes shined by a small boy working out in front of it. Even so, he'll still look down on Link unless he is wealthy enough to buy any of his wares (which is impossible, as the maximum amount of Rupees he can carry in the game is 1000). However, if enough money is donated to Malo at Malo Mart in Kakariko Village, he buys out Chudley and converts his shop into the Castle Town branch of Malo Mart, drastically reducing the prices of his wares.

Chudley remains in charge of the shop after this, but he changes his name to Malver and becomes completely opposite of what he was before: he now wears extravagant colorful clothing similarly to Fyer and Falbi, constantly dances a strange and almost hypnotic dance, acts very cheery, and is completely devoted to satisfying his customers. For example, if you buy some arrows, but don't have nearly enough room in your quiver to buy them, he'll tell you that you'd be wasting rupees, and ask hesitantly if you're sure you 'd like to buy them.

Trivia

 * Chudley is one of the few characters in the entire series who ever speaks in actual words. After buying the Magic Armor, he clearly says "Thank you".
 * Chudley's attitude change is similar to that of Bomb-Master Cannon's from The Wind Waker: they're both rude and snooty when they charge high prices for their items, but become nice and friendly once they reduce their prices.
