Deadly! was an Australian children's television cartoon series which first screened on the Nine Network in 2006 and kept airing until 2010. It was produced by Yoram Gross Productions and financed by the Film Finance Corporation Australia Ltd.
The series is based on the Deadly novel series written by Morris Gleitzman and Paul Jennings. The story follows the adventures of Sprocket and Amy, trying to escape and meddle with the plans of the Brats.
Amy is twelve years old, and has to look after her mother – who has just turned two. Sprocket is a runaway in search of his family – with only a faded photo to go on. Meanwhile, the seeds of a blue tea plant have been washed into the river system, and any moment now plants will grow that can keep people young forever.
Nevertheless, Amy and Sprocket have each other. Together they try to bring up Toddler Mum as best they can, fight Pooper Scooper and his malevolent family, and put an end to every one of those mutating tea plants before they can destroy the world.
