Morris has a great imagination. He paints amazing pictures and he loves his classroom's dress-up center, especially the tangerine dress. It reminds him of tigers, the sun and his mother's hair. The other children don't understand - dresses, they say, are for girls. And Morris certainly isn't welcome in the spaceship his classmates are building - astronauts, they say, don't wear dresses. One day Morris has a tummy ache, and his mother lets him stay home from school. He stays in bed reading about elephants, and her dreams about a space adventure with his cat, Moo. Inspired by his dream, Morris paints a fantastic picture, and everything begins to change when he takes it to school.
