The Island of Destiny

You try to hit in in the eyes so maybe you can blind it. It lowers its head to try to take a bite out of you. Realizing your chance you take your best shot and lunge your fist directly at its huge eyeball.

Unfortunately the dragon is much faster than you and in a split second, bites off your arm. You lie there on the ground, unable to fight anymore. However, the dragon is generous and puts you out of your misery in one swift, big bite.
