Certifying superheroes
I transformed a routine global hygiene campaign into a parent-child gamified pledge—turning tooth-brushing from a nagging habit into a shared superhero mission that drove real behavioural change.
THE CHALLENGE
Global health campaigns often arrive locally with good intentions and blunt instruments. Signal’s international “Brush Day + Night” initiative was no exception: a well-meaning drive to encourage better oral hygiene, aimed squarely at parents, and scheduled to roll out through a children’s puzzle booklet for BTL activity. But beneath the surface sat a more complex problem. Toothpaste consumption isn’t won through awareness alone—especially when you’re not the dominant brand. Behaviour change, not box-ticking, was the real prize. So how do you move beyond colouring-in compliance to genuine daily commitment? And more pressingly, how do you do that in 48 hours, on a budget already earmarked for a puzzle book, without alienating a client who simply wants the global brief delivered?
“David turned a simple hygiene message into a system that genuinely changed behaviour—without overcomplicating or overspending.”
THE SOLUTION
Rather than treating brushing as an instruction, I reframed it as a pact. The breakthrough was simple but powerful: if children and parents committed together, behaviour would follow. I proposed Signal Superheroes—a gamified system where brushing day and night became a shared mission, not a parental chore. The reward wasn’t toothpaste. It was status.
A purpose-built BTL activation turning a simple hygiene message into a hands-on superhero enrolment experience for children and parents.
To make the commitment tangible, we designed a certification mechanic. Children became superheroes by enrolling early—starting with a photograph of themselves in character. At pop-up booths, kids chose hero frames, popped their heads through, and were photographed on the spot. Within minutes, that image was printed and embedded into a personalised certificate—turning an abstract promise into something visible, owned, and proudly theirs.
The system was intentionally lightweight. One side of an A4 explained the “superhero mission”; the other became the certificate itself. Parents completed the name, explained the “special powers” (brushing), and verified progress using simple stickers—one for each successful morning and night. Complete the week, earn the final superhero badge, get the certificate signed, wear the sticker with pride. No apps. No lectures. Just commitment, recognition, and shared accountability—delivered within the original BTL budget by stripping away fluff and focusing on what actually motivates behaviour.
THE RESULTS
The response was immediate—and emotional. Parents didn’t talk about messaging; they talked about mornings transformed. One mother told us her son had never brushed consistently before—and now woke her at 5am to proudly announce he’d already done it. That’s not awareness. That’s behaviour change.
A tangible contract between parent and child, designed to turn habit-building into a goal-driven, shareable achievement.
Just as importantly, the client’s relationship with creativity shifted. What began as a puzzle-book request became proof that local strategic thinking could outperform straight global adaptation. Signal gained a campaign mechanic that worked with families, not against them—and the agency earned trust to lead creatively, not just execute. By turning a routine into a ritual, and a habit into a heroic achievement, we proved that when people commit together, change sticks.
