You start to play a tune on the flute, slowly moving it back and forth. The cobra seems mezmerized by the action. Then, after you have played for exactly thirty seconds, the cobra suddenly starts to change!
It gradually changes into a beautiful princess. She explains that a horrible Witch cast a spell on her which transformed her into a cobra, and the only way to break the spell was to use the golden flute!
Then, she says, "I'd better get back to my castle. It is under the sea so you can't go there. But here's a little present for you", she says, handing you a miniature statue made of pure gold.
You thank her and continue along the path.
