Zelda all night long!

Okay... I'm on the island with the group of kids and the schoolteacher. They have challenged me to a game of hide and seek. One of the kids is at the top of a tall pine tree. Let's ignore the question, just for a moment, of why there is a pine tree on a tiny tropical island and get to the real problem at hand. I can't seem to get to the kid to say "ha, gotcha". I can see him from a distance, from several vantage points, but I can't get close enough to interact with him. Anyone gotten this one yet?
