What's in the Box

Red and white striped top with cartoon rat prints
Distressed-effect trousers with sauce splatters and 'RATBURGER' text
Messy black shag wig
Black-framed glasses
Special Sauce bottle prop with sound chip

This Kids Ratburger Costume brings David Walliams' unforgettable anti-hero to life — the striped tee covered in cartoon rats, the paint-splattered trousers, the wild black wig and the sound-effect sauce bottle are straight from the pages of the book.

The red and white striped top has three-quarter sleeves and rat illustrations scattered across every stripe. The navy trousers feature red paint splatters, yellow sauce drips, and 'RATBURGER' printed on the waistband. The messy black wig adds instant disheveled-kid energy, and the Special Sauce bottle prop plays sound effects when your child waves it around — perfect for re-enacting the story's burger-van mayhem.

Perfect For

Book Week & World Book Day: A standout pick for any David Walliams fan — Ratburger is instantly recognisable to teachers and classmates who've read the book, and it's one of the few characters that looks genuinely mischievous rather than polished.

School Dress-Up Days: British children's literature parades, anti-hero character days, or any event where your kid wants to be the scruffy underdog rather than the shiny superhero.

Themed Birthday Parties: David Walliams-themed parties, book-lover celebrations, or just casual dress-up at home where the sound-effect bottle becomes the star of imaginative play.

How to Wear It

Pair with scuffed black trainers or Converse-style sneakers to complete the street-kid look. The wig comes ready to wear but fluff it out a bit for extra wild-child volume — synthetic fibres settle flat in packaging.

Parent FAQs

Q: What size should I order?

A: Check the size chart image on this listing — the top is loose-fitting jersey knit and the trousers have an elastic waistband, so there's flex either way. If your child is between sizes we'd say size up for comfort and longer wear.

Q: Does the sauce bottle prop actually make sounds?

A: Yes — it has an integrated sound chip that triggers when you shake or press the bottle. We test all electronics before dispatch, but if it arrives silent just reach out and we'll sort a replacement.

Q: Can they wear this over regular clothes, or does it replace everything?

A: This is a full outfit — the top and trousers replace your child's regular clothes. The elastic waistband means no fiddly buttons or zippers, so getting dressed for Book Week morning is quick. The wig and glasses slip on over the top.

Q: Is this suitable for Australian Book Week events?

A: Absolutely — David Walliams books are huge in Aussie schools and Ratburger is on many primary-school reading lists. Teachers love seeing British modern classics represented, and the costume is summer-friendly (short sleeves, no heavy layers).

Care: Hand wash top and trousers in cold water, air dry. Wipe bottle prop with damp cloth only.
