The brain-based heroes

Meet the brain crew

Captain Cortex never rides alone. Three brain-based heroes help kids steer through any Feelings Storm.

Captain Cortex

The brave leader inside your brain — he steers the brain-train through any storm.

Breathing Bella

She leads slow, deep breaths that find the calm center of the storm.

Detective Stretch

The crew's detective — he helps kids notice a big feeling and figure out its name.

Amy the Alarm

She rings the moment feelings get big — the signal to pause and check in.

Storm to steady

When the Feelings Storm rolls in

Four beats carry the brain-train from the first dark cloud to a clear, steady sky.

Beat 01 · The storm builds

Dark clouds roll in

Dark clouds gather fast and BIG feelings swirl — Anger, Frustration, and Disappointment spin up a full Feelings Storm.

Beat 02 · The signal

The alarm rings

Amy the Alarm sounds — the storm has a name. Kids learn to notice the feeling and say it out loud.

Beat 03 · The calm center

Pause. Breathe.

Breathing Bella leads one slow, deep breath. In the eye of the storm, Captain Cortex finds a calm center.

Beat 04 · Steady on

Steady on the rails

The brain-train rides out the storm. The sky clears, the sun breaks through, and kids learn they can weather any big feeling.

The first tool

Name it to tame it

In the book, naming the feeling is the first step to taming it.

Tap or press each storm cloud to name the feeling. Naming a feeling is the first step to taming it — once named, a cloud settles into calm and stays that way.

  • Anger
  • Frustration
  • Disappointment

Named. Tamed. Ready to ride the storm.

These clouds mirror the feelings Captain Cortex meets — Anger, Frustration, and Disappointment. Reading together, kids learn to spot and name their own.

Built-in life skills

What kids practice

The story shows the crew recognizing feelings, naming them, pausing, breathing, and asking teammates for help.

Recognizing emotions

Notice a big feeling the moment it rolls in — the first step to steering it.

Naming feelings

Put words to the storm — anger, frustration, and disappointment — and give the feeling a clear name.

Pause & breathe

Take one slow, deep breath to find a calm center — Breathing Bella's superpower.

Riding out the storm

Stay steady while the feeling passes — building real self-regulation.

Asking teammates for help

Call on the crew — no one weathers a storm alone.
