A campaign to teach children about copyright infringement on the internet, is employing cartoons and puns on pop stars' names, to get the message across.
The five-minute cartoons tell the story of would-be pop star Nancy, a French bulldog, who battles her ideas-stealing, feline nemesis, Kitty Perry, and teaches friends, including Justin Beaver and a rather dim Welsh sheep called Ed Shearling, about the importance of choosing an original band name and registering it as a trademark.
Most of the lessons are delivered by Nancy's sharp-suited but avuncular manager, Big Joe.
The Intellectual Property Office is leading the government's efforts to crack down on internet piracy and protect the revenues of Britain's creative industries.
The government agency is spending £20,000 of its own money on the latest Nancy campaign, which is part-funded by the UK music industry.
Catherine Davies, head of the IPO's education outreach department, which already produces teaching materials for GCSE students, admitted IP was a "complex subject" for small children and something of a challenge to make accessible and entertaining.
But she added: "In today's digital environment, even very young people are IP consumers, accessing online digital content independently and regularly.
"They are creators of IP, and many will leave school or university to take up careers in industries that depend upon inventiveness and creativity.
"A basic understanding of IP and a respect for others' IP rights is therefore a key life skill."
But some fear the IPO is being too heavy-handed in its warnings about piracy and that the message could backfire.
Jim Killock, director of the Open Rights Group campaign, said: "Some of the material seems misleading, in particular the episode explaining that downloading is the same as stealing from a shop.
"While it's wrong, it is neither the same in law - as downloading is a civil wrong while theft is a crime - nor is it a convincing analogy.
"The IPO risk educating children that copyright law is stupid and immoral by putting forward simplistic arguments like that."
Public information films - such as the much-loved Charley Says campaign - warned a generation of children about the dangers of playing with matches or going off with strangers
The genre has declined since its 1970s heyday, although Charley the cat made a comeback in 2014 in an electrical safety campaign voiced by comedian David Walliams.
But government departments have also been turning to cartoons to educate very young children about boring and complicated subjects
In 2016, HM Revenue & Customs produced a Junior Tax Facts video for eight- to 11-year-olds, which explained, among other things, that the VAT on sweets meant they were taxpayers too
