Beedle

Beedle is a recurring character from the Legend of Zelda series. He is a traveling merchant whose hairstyle resembles that of Paul McCartney, a member of the famous band, The Beatles, a likely derivative of his name.

The Legend of Zelda: The Wind Waker
He has a shop boat, and travels all around the Great Sea. He also has a special ship where Link can buy rare items. Beedle uses a points system, giving Link points for every purchase he makes. After acquiring enough points, Link will receive a discount on the items he buys. Interestingly, Beedle has voice acting; he clearly says "Thank you!" after Link buys his items and gives a farewell of "Byyee!" when ending the shop dialogue.

The Legend of Zelda: The Minish Cap
If Link performs a certain Kinstone fusion, Beedle will appear in Hyrule Town's market. After this, he will sell Link Picolyte, which is a substance made by the Picori. Picolyte causes certain effects, such as finding more Kinstones, Rupees, Mysterious Shells and others which can be obtainable after bringing a picori the right ingredients to make the new Picolyte. These newer Picolyte are sold for more than the regular Picolyte.

The Legend of Zelda: Phantom Hourglass
Beedle wanders the sea in his shop boat and sells treasures, including Ship Parts, potions, and rarer items, such as Pieces of Heart. He also uses the points system, in which Link receives one point for every 10 Rupees he spends. As Link climbs the ranks of membership, he gets discounts and various Membership Cards.
