First, you must travel to the top of the mountain. As soon as you see the dragon, it should already be partially groggy. Keep going because for the minute you think he's sleeping, he'll wake up and burn you to a nice golden brown and then eat you like the delectable treat you are...
If you manage to get him to sleep, you've done the first part of your job. The second is to get the stones to go right up to the dragon and put a little jar under its mouth and catch the drool. You've only got about ten minutes before he wakes up. Oh, you didn't know that dragons only took cat naps? Yep. Pesky devils, aren't they? After nine minutes, grab that jar and run down the hill. When the dragon wakes up, he's going to be VERY hungry.
Now for the fun part: drinking the drool. Just take a sip. It tastes just like licorice!
Now that you've mastered the art of coaxing dragon drool, you can do anything. You can ride a bike. You can braid your hair. You can eat artichokes. You are the master of your domain.
