Against your better judgment--what's left of it at any rate--you make a mad dash for the opening with the steep downward slope. Something about the whole situation reeks of deception, and you have a vague recollection that you've seen this opening before...while being chased by marshmallow men who were shooting lasers. As you approach the opening, you see that the slope is much steeper than it first appeared, and you can't see where it leads. Just then, you notice a big red button above the opening.
You decide against just diving blindly into the opening, and, in a flash of what could be called intuition, you punch the button. This results in two other openings being revealed to the right of the steeply sloping one. You pause. The first of these new openings reveals a tunnel that ascends slightly, and curves gently away to the right. Oddly, it seems to made of stone, unlike the rest of what you have seen of this strange place. You can hear the faint sound of dripping liquid coming from the tunnel. It is lit from above, every two meters or so, by small lights with wires connecting each of them The second new opening reveals what appears to be a hallway, lit in the same manner as the first, lined with pictures of various types of bird-like lizards wearing very ... um, unique clothing. You can just barely hear odd animalistic noises from some point far down the hallway.
