Bagu is a male character that resides within the woods north of the river in The Adventure of Link. Link must speak with him in order to acquire a note which allows passage between the two sides of the Water Town of Saria and Death Mountain. Bagu bears a resemblance to Error of Ruto, another man who gives Link assistance in his quest. A friendly Bot in Saria will give a hint regarding Bagu's whereabouts if Link talks to it several times.
A sleeping monster in the Water Town of Saria. Poke it a few times...
