When does Midnight Patrol: Adventures in the Dream Zone return?

The show is about four children who meet in their dreams every night to protect the sleep of the innocent from the dreaded Nightmare Prince. The series revolves around Potsworth, an English Springer Spaniel, based upon a real-life springer spaniel. In the United Kingdom, the BBC felt that the suggestion of children being awake after midnight was inappropriate.
The series tells of four children and Potsworth the dog who live in the same neighborhood. When they go to sleep at night they turn up in the Dream Zone where they are appointed by the Grand Dozer to protect it from nightmares and other threats.
