Maria is reading her favourite story Room on the broom by Julia Donaldson.
To the annoyance of her cat a kindly witch allows a dog, a bird and a frog who have helped her retrieve things she has lost to ride on her broomstick, making it top heavy. The broom is destroyed by a fire-breathing dragon who threatens to eat the witch but the creatures band together to impersonate a monster and save her. As a result she fashions a luxurious new broom with seats on which they can all ride comfortably.
