Swamp Tourist Center Guide

The Swamp Tourist Center Guide plays a minor role in two  titles.

Ocarina of Time
In Ocarina of Time, this burly character is the owner of the Castle Town Bazaar, purveyor of shields and other goods. Apparently, he's a friend of the Death Mountain Trail Guard. If Link purchases a shield from him and tells the Bazaar Owner he was referred by the guard, he'll give the young hero a discount.

Majora's Mask
In Majora's Mask, the Swamp Tourist Center Guide runs the Swamp Tourist Center and accepts Link's entries for their Pictograph contest. He is the father of Tingle and is apparently ashamed of his son's obsession with fairies, which he finds irreconcilable with his age. If Link shows him a pictograph of either Tingle or the Deku King, the Swamp Tourist Center Guide will reward the young hero with a Piece of Heart.

Trivia
The man who runs the Swamp Shooting Gallery has the same model as the Swamp Tourist Center Manager.
