Interesting things on Zelda you may not of noticed

[Hawk]

I'm at around 43 hours I think. I am on my way to the snowy mountain.

I was curious what you get when you get all the poe souls, and what you get when you find all the bugs.

I just want to know if it'll be worth trying to find all the poe's and bugs, or if I'll feel it was a waste of time once I've spent all the time doing it.
