Matt was walking in the forest near his village while he smelled smoke and saw a fire that was out of the control. Many trees have already been burned. He looked at the black ground and saw a green snake, that was trapped under a large tree. He knew the snake was in danger. He lifted up the falling tree, put the snake into a bag and ran back to his village.
