I was walking in Yellowstone National Park when giant hands started coming out of the ground.They began grabbing people and pulling them under.I was running for dear life, dodging hands.I climbed a sturdy tree where I thought I would be safe but I was wrong A hand came up very slowly.It was ready to attack but in half a second a man dressed in black with one word stopped them all.I tried to thank him but he disappeared down the path.He dropped something on the ground.I picked it up. It was a badge that read: M G.What can it mean?
