Hall of Infinite Doors

What you thought originally to be a map turned out to be a series of drawings that are supposedly a way to get out of this massive forested greenhouse. You gather from these diagrams that there is a special seed hidden somewhere in here that will instantly grow into a staircase to the upper level of the greenhouse where three treasures must be acquired to open the door back to the hallway. As you study the mysteriously acquired paper a bright red bird swoops from the sky and steals it from you. You try to see where it flew off to but the bright sun prevented you from gathering any idea where it disappeared to.

The sun has now risen and you slowly realize how hot it has become. The boiling river doesn't look very inviting. You need to find another way to cool off quick.
