Ulrira

From Zelda - Wiki on Neoseeker

Ulrira is a shy yet knowledgeable old man from Link's Awakening. He lives with his Wife in the house south of Madame MeowMeow's house in Mabe Village. All day, he sits inside on his rocking chair, waiting for phone calls. When spoken to in person, he can barely even utter a complete sentence, but if you call him from one of the phone booths found all across Koholint Island [See Map], he will answer with advice that applies to your current quest in the game, regardless of where you are. These phone booths are small buildings shaped like trees, and can be easily recognized by the large telephone atop the roof of each one.
