Smoke is an invisible dragon,[dubious - discuss] who will only communicate with Tracey Simmons, aged 3, and often acts to cause Simmons to get into trouble with her parents.[citation needed] Adults generally[who?] refuse to believe that Smoke exists, citing the non-existence of invisible dragons, although Tracey's friends at nursery say they have heard Smoke. Scientists as yet are unable to explain the phenomenon.
