Schools across Swansea have issued letters to parents today to remind them that Frozen isn’t a book and dressing your child as Elsa is completely irrelevant for World Book Day on the 1st of March.

The letter has caused widespread panic in the city, with many parents now wondering what they can dress their children up in.

Education Department spokesperson Theresa Connell said: “An astonishing number of children were dressed as Elsa last year, which goes some way in explaining why our Pisa results are so terrible.

“There’s so many options. Disney is crap in literary terms and those Elsa costumes give our Health and Safety Manager nightmares, especially as our schools are so dilapidated and underfunded we have to fill them with heaters we can’t afford to PAT test.

“Your children could have a red nose painted on and come as Swansea’s own Dylan Thomas. Or the Gruffalo.”

Parent Pete Bowen said: “The reason my daughter has a head in the shape of a shovel is because she’s been laid flat watching Disney DVDs since she was born.

“Who wants to dress up as a book? Not my daughter. She wears flammable princess dresses all the time, she’s my princess and she loves being a princess because she’s a little girl, so by default she can only dress up as a princess.

“The Council should let it go.”
