A forest! This area has a forest ambiance sound that plays parallel to the music. It's made of win. And yes, I'm aware at how disgustingly generic the name of this location is; it's made of nerf and lose.
TheDave is probably wandering around here somewhere. This area has a lot of forest canopies that obscure vision. You can move under the canopy and find hidden areas. Watch out for hostiles.
In the image above, you'll notice a sparkley thing. It's a save point! You can save your progress and use Hero Meals from these. There are a few areas you don't have to find one of these to save (e.g. safe areas).
Kracka-boom! Dark clouds roll in and the forest slowly gets deformed in to a swamp. A bunch of new hostiles spawn as the area changes. What's with this messed up weather? Plot hook!
