Final Quest

"I think that we should continue and try to find what we're looking for as quickly as possible," you say. "I think that if we stay here for much longer, we'll lose our minds."
"You're probably right," the green dragon agrees. "I'm getting this sudden urge to fight anyone I see."
It is perhaps to your peril that you do not pay attention to those words.
"There they are!" the green dragon shouts, pointing a claw to two pale stones lying on the ground.
Suddenly, a huge snake appears out of nowhere. It lowers its head to you. -FOOLISH ADVENTURER!-
You scream, and clap both hands over your ears.
The snake looks at the green dragon. -DO MY BIDDING.-
The green dragon starts coming towards you, obviously intent on killing you.
What are you going to do?
