You reach the end of the tunnel and see a sleeping dragon curled up in the distance. You think fast and see you have two options...
Run all the way back to the entrance of the cave.
Go up and softly wake the dragon while singing to it to keep it calm. When it wakes up completely, you pet and befriend it creating a life long bond between you and it so whenever you think of it, it will come flying to see you and will protect you and bring you anywhere your heart desires.
