The children think that the boy in the blue and silver suit is from space. They try to talk to the boy, who they call peep-peep, but they are not sure that he understands them. Helen goes to tell Mr Bunting about peep-peep but Mr Bunting doesn't believe her. The children take peep-peep to Mr Bunting who shows the boy a star chart. The children and Mr Bunting find out that peep-peep's spaceship was collecting meteorites from Mars before arriving on Earth. Peep-peep tries to write something for the children but they can't read it. Peep-peep collapses.
