None of our themes quite right? We'll build a completely custom birthday party box around your child's passion — their favourite character, world, obsession, or dream. Get in touch and we'll co-create it together.
How it works
Message us on WhatsApp or by email. Share your child's age, what they love, the party date and how many guests you're expecting. The more you tell us, the better the party we can build.
We'll come back with a theme concept, activity outline and what we'll include in the box. You give feedback, we refine it. This is a real collaboration — your ideas, our expertise.
Once you're happy, we pack the full custom box and deliver it to your door — complete with PartyPilot guiding you through every single moment of the party.
What we can build
Every custom box includes everything in our standard boxes — fully themed to match your child's world.
Backdrop, balloons, table props and scene-setters — all designed around your chosen theme. We source and include everything.
Character-matched props and gear so every child steps into the world from the moment the party starts.
Clues, riddles and a hunt designed around your theme — adapted to your child's age group.
Theme-matched makes that every child completes and takes home. All materials included and pre-portioned.
Themed games matched to the energy and age of your group — scripted in PartyPilot so whoever is hosting knows exactly what to do.
A personalised opening video from a character in your chosen world — your child's name, spoken live. The moment every party starts with a gasp.
A custom climax moment — the reveal, the treasure, the mission complete. Designed to be the thing they talk about for weeks.
Theme-matched goodie bags for every child. Nothing for you to source, wrap or assemble separately.
Some ideas to get you started
These are just a few starting points. If it's not on this list, tell us anyway — the stranger the better.

"My son is obsessed with volcanoes. I didn't think anyone could turn that into a birthday party. They did. It was the best two hours of his life."
