Bagu

The master of the town of Saria. Link finds Bagu in a thick, wooded area. The river guards of Saria require his permission to allow outsiders to cross the bridge that leads to Death Mountain.

It is likely that the name Bagu is a joke from the developers, since he is close friends and quest-related to the character Error. "Bagu" would be the romanization of the Japanese way of writing the word "bug". As such, "bug" and "error" refer to a computer's malfunctioning.
