There are areas where I can see fruits that you can normally pick up, such as in the desert, but they're in areas I can't get to. Do those areas eventually open up, or do they just remain closed? In the desert, there's an elevated area near the store, to the right of the dinosaur bones, where there's a cactus fruit. If there's a way to get up there, I haven't found it. There are a couple of other areas that are inaccessible, and I'm a couple of years in.
