Old Man Ho Ho

From Zelda Wiki.org

Old Man Ho Ho is an elderly man who can be found in many islands of the Great Sea. He usually is seen staring through his telescope looking at places of interest where treasure or special items can be found. When spoken to he also gives subtle hints to what or where the place is that he is staring at and what can be found there. Sometimes he is looking through a kalidoscope.

Based on information from Phantom Hourglass, he comes from the land of Wayaway, and is apparently a member of the Ho Ho Tribe.
