Numberjacks

Numberjacks is a British children's television series that originally aired on BBC2 in the UK between October 2006 and 2009; re-runs of the episodes are still shown regularly on CBeebies (when it was on BBC2, it was only on occasionally, and when it first appeared, it was only on for a week). It was produced by Open Mind Productions for the BBC and features a mixture of computer-generated animation and live-action.

Synopsis

The Numberjacks are animated characters (the numbers 0 to 9) who live in an ordinary sofa and solve problems outside; each episode has the same structure. At the beginning of the episode, some of the Numberjacks are engaged in an activity, that would have relevance to the problem that is later discovered - then, an "agent" (who was a live-action child) calls in and describes the problem that is occurring. One (or two) of the Numberjacks go out into the real world to solve the problem while the remaining Numberjacks stay in the sofa and watch their progress on a screen. As soon as the problem is understood, 5 imagines what else could go wrong if it wasn't solved (often wondering what would happen to the Dancing Cow, who never actually made any physical appearance in the real world).
