Business Scrub

Business Scrubs are found in Ocarina of Time, Majora's Mask, Oracle of Seasons, Oracle of Ages, and The Minish Cap. They are not significant characters in any of the games, but they do enable Link's discovery of several Heart Pieces throughout the game.

Ocarina of Time
In Ocarina of Time, Business Scrubs appeared in a multitude of places. Many were found underground, selling items such as Bombs, Arrows, and Deku Nuts. One scrub could be found in Dodongo's Cavern, selling Deku Shields, since fire was an element in the cavern, and Deku Shields burn easily. Another can be found in Hyrule Field down a hidden hole nearby the entrance of Lake Hylia. After it's defeat, it will offer to sell you a Heart Piece for a mere 10 Rupees. This is very different from past encounters with Business Scrubs as they usually try to sell you small numbers of ordinary items, that can be found for free, for high prices.

Majora's Mask
Business Scrubs appear in Majora's Mask in various locations. In this game, they are part of a larger process. The process starts by collecting the Moon's Tear from the Astral Observatory by looking through the telescope. Once Link acquires it, he can go to the yellow-colored flower in South Clock Town and talk to the scrub there. Once Link shows him the Moon's Tear, he will become excited and give you a Land Title Deed, giving Link permission to use the flower. This is important at the beginning of the game, as it is the only way to get to the top of the Clock Tower at this time. Deku Link may use the flower to fly to the Clock Tower.

Later in the game, Link can exchange this Land Title Deed for various other Deed in the Southern Swamp, Goron Village,Great Bay, and Ikana Canyon regions. If Link approaches the Business Scrub in the Southern Swamp, the Scrub will profess a desire to live in town. He will exchange the Swamp Title Deed for Link's Land Title Deed. A Scrub in Goron Village will exchange the Mountain Title Deed for the Swamp Title Deed when approached as Deku Link. In Lulu's room of Zora Hall, another Business Scrub will exchange the Ocean Title Deed for Link's Mountain Title Deed when approached as a Goron. The final Scrub is located in Ikana Canyon, and he will simply take the Ocean Title Deed, leaving the Deku Flower behind.

Oracle Series
In the Oracle games, Business Scrubs make another reappearance. The Business Shrubs are hidden underneath certain bushes or stones, which cannot be cut or destroyed, and will pop up when Link walks near them. Unlike other incarnations of Business Shrubs, most Business Shrubs in the Oracle games will not attack Link. These Business Shrubs are often hidden among other bushes, making them not stand out so much. The Business Shrubs often sell Wooden Shields, and their prices can vary from Shrub to Shrub.

A few Deku Shrubs in the Oracle games do attack Link by spitting seeds at him, which can just as easily be deflected with the use of a shield.

The Minish Cap
Quote from The Legend of Zelda: The Minish Cap Business Scrub figurine: "Appears in caves, etc. Normally stay underground. They'll pop out and spit seeds at you, but if you get to know 'em they're not so bad."

The first Business Scub you meet says that it keeps spitting out seeds when it talks to you. Kind of sad.
