The Sahara desert was harsh and unforgiving. You hadn't enough water to last the week, and your plane was in no state to fly.

On the first night, you had simply fallen asleep on the sand a thousand miles from all human habitation. You were more isolated than a shipwrecked man on a raft in mid-ocean. Why, then, were you woken at daybreak by a funny little voice?

"If you please - draw me a sheep!"

You blinked your eyes open, groggy from sleep, and found a young boy with hair like golden straw before you.
