Park In The Dark by Waddell Martin

A hugely endearing picture book from the makers of the Big Bear and Little Bear series. When the sun goes down and the moon comes up, the toy monkey and his friends, Loopy the elephant and Little Gee the dog, creep softly out of the bedroom, down the stairs and through the dark hall on their way to the deserted park. The park's an exciting place to be after dark, though a little bit scary - especially when the Thing (a night train) hurtles out of the darkness, seeming to chase them.
