Midnight Patrol: Adventures in the Dream Zone is an animated series produced by Hanna-Barbera in conjunction with Sleepy Kids PLC and is known outside the US as Potsworth & Co. In the United Kingdom, the BBC felt that the suggestion of children being awake after midnight was inappropriate (which is reflected in the theme song's lyrics in the British broadcast); thus the name was changed. The show is about four children who meet in their dreams every night, accompanied by their dog Potsworth and a toy dinosaur, to protect the sleep of the innocent from the dreaded Nightmare Prince.
