The Wow Moment

A child sees their hourglass bracelet pulsing orange and yells "Mom, I need 50 more bounces to refill my sun shield!" — sprinting to the trampoline, jumping with genuine excitement, then proudly presenting their glowing green wrist to get sunscreen applied.


The same kid who previously hid when they saw the sunscreen bottle is now demanding it because they "leveled up" their sun protection.
