The Doctor and Amy stood on the edge of the Grand Canyon in the hot Arizona sun. "Wow. All of time and space and I'm still amazed by the little things," the Doctor said happily. "You call this little?" Amy replied. "Well..." the Doctor muttered. She rolled her eyes. "Come on, we've got 3 more Natural Wonders of the World to see."

They walked past the parking lot into a small clearing where the TARDIS was hidden. "Great Barrier Reef, here we come," the Doctor said putting his key into the lock. Then a loud scream came from deeper in the clearing. The Doctor and Amy looked at each other then took off into the clearing. Amy heard the sonic screwdriver as she carefully searched for the person screaming. She could find no one.

"No, no, no," the Doctor said quietly. She paced back to where the Doctor was standing. "What is it?" "Take a look at this," the Doctor pointed at giant, bloody claw marks on nearby trees. "What are they?" "Claw marks," the Doctor pointed out. "I can see that," Amy softly hit him. "What made them?" "Windigo," he sighed. "We've got a Windigo."

"What does that mean?" she asked. The Doctor sadly smiled. "Back to the TARDIS." Amy relunctantly followed him. "What?! Doctor! Are we just going to let that person," she pointed back into the clearing, "die?" "It's a Windigo, Amy. They can mimick human screams to lure people towards it," he said pushing the TARDIS door open. Amy put her hands on her hips. "So, we're just going to let it stay here and eat people?" "No," he replied with a small smile.

Amy looked at him questioningly as she walked inside the police box. "Now," he said as he closed the door behind him, "let's get going!" "Where?" "Kansas!" he said as he flipped a switch. "What's in Kansas?" She fell to the floor from the bumpy take off. "Help," he answered. It felt like the quickest ride of her life. All of a sudden the box landed with a thud.
