Three mornings.
One new detective.
Kids investigate big feelings like real cases. Badge, magnifying glass, and three suspects: General Grumpy, Captain Calm and Hip Hip Hooray.
The Grumpy Volcano
Three cases every kid needs to crack.
One suspect per morning. One real tool to take home.
The Grumpy Volcano
General Grumpy · Hot chest. Fists. Explodes without warning.
"He hides in fingers, jaws, and the words you swallow."
The Grumpy Stone
Squeeze + breathe = the meltdown stops before it ruins the evening.
The Wandering Mind
Captain Calm · A witness, not a suspect. Hides in plain sight.
"Follow the breath — you'll find where the attention went."
The Calm Jar
Shake — thoughts swirl. Wait — they settle. Just like the breath.
The Forgotten Joy
Hip Hip Hooray · Mission leader. Helps close the case with a real celebration.
"One Hooray in each finger — five to take home."
The Hooray Card
Their handprint, their evidence. For the nights that need it.
Not yoga with detective stickers.
Detective work is the spine. Yoga, breath and mindfulness are the tools detectives use to crack their cases.
Kids don't sit on a mat — they earn the right to be on the case.

That's what you hear after Heart Detective. Not yelling 'calm down'. Not meltdowns. A kid who names their own feelings — and knows what to do with them.

Questions Chiefs ask.
What ages is this for?
Kids 5 to 12. We adapt the casework to age — younger kids notice and name, older kids investigate.
My child has never done yoga.
Even better. We don't call it yoga — we call it evidence reenactment. Every pose is a clue in a real case.
Can my kid join just 1 or 2 mornings?
Yes. Each morning is a complete case with its own beginning, middle, and case closed. The full 3-day mission gives them the complete toolkit + certificate.
Is there a minimum number of kids?
Yes — we run with a minimum of 5 detectives per day. If we don't reach the minimum, you get a full refund automatically.
What if my child is shy?
Heart Detective is designed for them. No performing. No audience. Just observing, noticing, and earning stamps.
Bilingual?
Yes — Dutch and English, we adjust the balance based on the group.
Case file #001 opens July 6.
Twelve detectives per HQ. Six weeks to crack. One summer that changes everything.
