Here, some stone blocks that thrust outward when their corresponding colored block is triggered. The first one is a sample on how they work. Grab the sapphire in the pot just above the orange push block.
Descend just under the orange pressure plate and a pot containing a sapphire to the far right can be seen very near to a snake.
Continue going down and hit the crack on the wall twice to drop down. Pull the gray lever to push the snake out of the way with the push block.
Also to the left of the screen, a pot can be seen containing a Frozen Spider fragment. Make your way up and grab the spear. Stand in front of the orange push block and throw the spear at the snake to depress the yellow pressure plate. Show yourself to the now visible lizard to make it chase. Make your way in front of the orange push block. The lizard will step on the plate, pushing you down the lower level. From here, it is a clear shot to the next area.
