Jak and Daxter: The Precursor Legacy/Geyser Rock

During the opening cinematic, Samos the sage sends Jak and Daxter through the warp gate in his house to Geyser Rock for some practice. Once get to Geyser Rock you see that it is a small tropical island with many geysers on it (hence the name). There are no enemies on the island except for the lurker shark. As long as you stay out of the deep ocean water you don't really need to worry about it.
