Jak and Daxter: The Precursor Legacy/Demo

After watching the Intro Movie, you will already be on Misty Island. Apparently in the real game, you start out on or near Lookout Island where there is a small village.

For purposes of the walkthrough, the guide separates the island into areas for clarity of item locations.

Demo Story (intro movie)
Jak and Daxter visit the local wiseman to see if they can find some information on how to turn Daxter back to normal. The wiseman says he has been watching the Lurkers trying to obtain the source of Dark Eco on the nearby Misty Island. He decides to send Jak and Daxter to Misty Island to stop the Lurkers.
