The height of the cave was quite less, but Keith could still crawl inside if he wanted to. The entrance was also hidden pretty well, thanks to various vines, leaves and a few medium sized stones. While he could crawl inside, he didn't bother doing it at all.
Instead, he put his index finger to his lips and motioned the others to keep quiet while he grabbed a few dry and wet sticks before stacking them on top of each other, into a pile. He then grabbed a few specific leaves and stuffed them in between the sticks before he used his magnifying glass to light up a fire.
It took two minutes, but it worked. The dry sticks caught fire while the wet sticks produced smoke. Keith took off his shirt and gently waved it in front of the fire, sending the smoke into the cave. He continued doing this until he heard a rough cough from inside the cave and smiled.
