ПОМОГИТЕ УМОЛЯЮЮЮЮ!!!! ВЫПИСАТЬ ПРЕДЛОЖЕНИЯ О ПОБЕГЕ ИЗ БАШНИ!!!!The next morning there were a lot of tourists with cameras in the Tower. But Walter, Mary, William and Anne were glad to see the people. The more people that were in the fortress, the more chance they had to escape. ''Let's get over to the tower. That's Where most of the people go first,'' said Walter. So the four ravens went to the tower. A large group of tourists came by. The people put their bags down because there was a long line. They didn't want to hold their heavy bags that were full of souvenirs.''Aha! Bags! Plan number one. Okay one. Okay everybody, find a bag and get into it,'' Walter told the ravens. Walter, Mary, William and Anne Walked Along the ground near the tourists' feet. William jumped into a bag. Mary got into another bag. But it was full. She moved sweets, souvenir plates and flags around and finally got to the bottom of the bag. She stayed very still. Walter found an open bag. There wasn't very much inside it. He laid down very quietly. Anne saw the tag she wanted to jump into . She saw tried to get in but she couldn't manage it . Anne landed near the woman's leg and scracthed her with her beak .
