A pufferfish family needed to cross a maze-like ocean ravine. The kids engineered a magnetic rover to carry them through — no hands allowed.
Mission 19Turtle Tumbleguard
A fragile desert-tortoise egg had to survive a drop from a windy mesa. The kids engineered capsules to land it soft.

A little glow-lizard was lost in a dust cloud. The kids engineered swirling 'sunset bottles' to make him a calm home until it cleared.

Little ash-cats were trapped in a sealed crater. The kids built lever-arm launchers to fling rescue pods to safety — and discovered physics along the way.

A dark dragon feared the light. The kids engineered layered 'light shields,' testing how different materials pack together.
Mission 25Mysterious Materials
Five jars of unknown powders appeared. The kids became Chemical Detectives, running real tests to identify each one.

To reach the villains' fortress, the kids built towers, bridges, and a working pulley to hoist their tiny spider allies up the walls.
Mission 27The Enchanted Forest Fighter Tree

With the Heart of the Forest stolen, the kids crafted a full set of battle gear — shield, sword, and helmet — mastering how the body's systems work together.
Mission 30The Monarch Sanctuary
Charged with saving monarchs from a freezing blast, the kids became Insulation Engineers — building sanctuaries and reading real thermometers to prove they worked.
Mission 32Santa's Sleigh Rescue
With the sleigh dismantled, the kids rebuilt a delivery vehicle strong enough to carry presents — and survive a high-speed ride down the slide.
Mission 34The Sun-Seeker's Sanctuary
After a daring zipline rescue, the kids designed sun-tracking lizard homes — orienting windows to the sun's path and using real power tools to build them.
Mission 35The Great Snack-Stronauts
With a giant chalk map of the U.S. as the launchpad, kids built paper rockets and launched them 'across the country' — learning directions as they flew.
Mission 36The Treasure of Emma Prusch Farm
The kids built working Galilean telescopes, then used them to crack a symbol code and follow a hand-assembled map to buried treasure.
Mission 38The Cricket Courtyard
The kids became System Stewards, engineering a bio-active habitat where crickets, isopods, worms, and a chia-seed forest all work together.
Mission 39Hornworm Habitat Build
Instead of just 'keeping' a creature, the kids asked what it truly needs — engineering a full-life-cycle habitat for their hornworms.
Mission 40The Critter Allies
Invent a creature so strange no villain could stop it — then build it from scratch.
Mission 41The Fulcrum Flip
Starting at the seesaw, the kids discovered the lever — then built their own launchers and used one to free a bucket of bricks from a villain's trap.
Mission 42Pulley Power
On St. Patrick's Day, the kids learned the pulley — threading their own systems to build leprechaun traps with drop-fast cages.
Mission 43The Getaway Car
To rescue a newly-legged tree frog, the kids built balloon-powered cars — reasoning about an invisible force they couldn't see, only test.
Mission 44The Siege of Tangle's Fortress
The most ambitious build of the year: hand-cranked trebuchets to lay siege to a villain's fortress — a hard, humbling, wonderful morning in the rain.
Mission 46The Squirrely String Band
A noisy villain thought louder was always better. The kids built string instruments and learned a tune together — proving music beats noise.

Using real copper pipe and real tools, the kids built five-note chimes — then tuned up and played a song together as a group.

The kids met the building blocks of every story — character, setting, problem, solution — by crafting fairy peg dolls and acting out their tales.
Mission 49Character & Performance
The storytelling unit shifted from the 'where' to the 'who' — kids built original characters and stepped onto a real stage to bring them to life.

Living the Three Little Pigs, the kids built houses of straw, sticks, and bricks — then stress-tested each one against the Big Bad Wolf's breath.
Mission 51The Three Little Pigs
The grand finale: casting roles, painting giant cardboard houses, and crafting pig snouts and wolf masks for the end-of-year play.
