Deserted Desert

The bright sun beamed down on the ever-changing sand in the desert... Struggling to walk, Joe stumbled across the sand... Feeling weaker and weaker and weaker. Joes vision started to become blurry, he kept seeing mirages appear..
"So thirsty... Need water.." Mumbled Joe. He needed to fine water fast!
It was getting dark, Joe needed some where to stay for the night... But he was in the middle of a desert...Where is there to stay in the middle of no where?
"Oh... Nearly there..!" Joe cried.. He'd found a cave burrowed inside of a sand hill. Luckily, he was able to sleep.. He found it hard though, because of the heat, dry mouth and worry.
If he stayed at home, rather than going out to explore the world, none of this would ever of happened!!
Oh the heat! The sun was glaring down on Joes head.

'RUMBLEEE!!' Joe was starving! He went to search for some food.. But nothing..
Just then, Joe realised that he had 1 flare left! So within seconds, Joe let it off.. What's going to happen now?
