Hall of Infinite Doors

You kick the tree's trunk. In retaliation, one of his lowere branches hits you in the midsection and you go flying along the ground. You land next to a flowing river. At this point you realize how thirsty you are, too. You begin to drink straight from the river. You drink with such energy that you fall into the river and the current takes you away. You pass out and awaken hours later still trapped inside the greenhouse. Now the sun is shining brightly through the ceiling. You may be able to see more clearly now but the heat is unbearable. You attempt to return to the river but you are surprised to see that the water is boiling. Obviously that isn't going to cool you down. You need to find another way to cool off or you're going to die of heatstroke.
