Emu's World.

In 1981, Rod Hull was offered the opportunity to make a series for younger children by the newly-awarded ITV franchise Central Independent Television. This led to the birth of the Pink Windmill in which Rod and Emu lived, the green witch named Grotbags (played by the singer and comedienne Carol Lee Scott), and her hopeless assistant Croc. The premise of the show was simple: each week Grotbags attempted to steal Emu so that, once captured, (in Grotbags's own words) she would be able to use its "special powers" to control all the "brats" in the world. Children from the Corona Theatre School—referred to collectively as the Pink Windmill Kids—were on hand to offer protection and break into one or two song and dance routines per episode. The show featured Rod Hull's chanted catchphrase "There's somebody at the door, oh, there's somebody at the door" every time a visitor rang the doorbell of the Pink Windmill—which 'sneezed' loudly when pressed.
