Tom was sat there listening trying to figure out when you would have to change something or someone into an animal, he knew all the one's other people were coming up with, but he wanted to say something different, okay he had an idea. He raised his hand and smiled. 'Let's say when you meet two aliens from another planet and they are being chased by someone, then you could change them into an animal and hope that the other people don't find them, until you can get them back to their spaceship!' It could happen right, there could be life out there in the universe.
