Dorothy plays with a friend who is into dinosaurs -- the girl crawls around on her hands and knees and roars. This isn't really up Dorothy's alley, but she has compromised with the friend and will play dinosaur. This is the dinosaur she agrees to: "Its name is Dorothy-o-saurus and it's purple, it stays a baby forever, it lives forever, it eats plants, it can walk on two feet, it can jump over a tree, and it learns how to protect itself as soon as it's born."
Dorothy refers to her hem as "the rim of her dress."
