They looked like kangaroos,giant kangaroos. Following them was a huge monster. It looked almost human except that it had a single,huge,red,glowing eye. The monster turned to close the door and shouted,'Good night,friends.' The friends outside shouted,'Good night, Gork.' Then Gork shut the door,turned round and saw us. He gave a roar that turned our blood to ice. 'Aliens!Aliens in my cave.How did you get in here?' I thought fast,and said quietly, 'Good evening,Mr Gork. My name is Nobody and these people here are my ...' Gork roared again,'I know who you are. You're aliens and we kill all aliens in this valley. That's our custom. Tomorrow,at dawn, you are going to die!All of you.' Before we could move, Gork pressed a button on the wall beside him. Steel bars sprang from the ground around us and closed over our heads. We were caught like rats in a trap. Gork pressed another button, and a powerful magnet above the cage pulled our guns from our hands.
