In animation, a girl with brown hair named Lucita Sky jumps off a trampoline and meets a bird up in the air. She flies alongside the bird.

A chorus sings a song that goes IF YOU'RE A KID
WITH POWERS
THEN WHERE'S
THE PLACE TO BE?

Then at the park, a boy with red hair named Benny Bubbles tosses a ball to his dog and shoots bubbles with the move.

At home, a super strong girl with black hair in piggy tails named Sara Snap lifts up a sofa with one hand.

The song continues
IF YOU HAVE SUPER STRENGTH
AND CAN LIFT
A TON OR THREE
YOU BELONG
AT HERO ELEMENTARY

At his desk, a gadget-creator boy with curly brown hair named A.J. Gadgets figures out how to make his rocket ship better.

The song continues IF YOUR
POWER LETS YOU FLY

Now in her purple superhero costume, Lucita sings YOU'RE LIKE ME,
LUCITA SKY

The song continues LIKE TO HELP OUT
WHEN THERE'S TROUBLE?

In his superhero costume, Benny makes bubbles and sings OH, YOU BET,
I'M BENNY BUBBLES!

The song continues TELEPORT
IN NO TIME FLAT?

Sara sings SARA SNAP CAN,
JUST LIKE THAT!

The song continues USE SUPER TOOLS
TO SAVE THE DAY?

Wearing his superhero outfit and jetpack, A.J. says LIKE AA.J. says GADGETS,
I'M ON MY WAY!

The song continues HOW DO THEY SAVE THE DAY?
WELL,
THE SCIENTIFIC FACT IS
THEY USE
ALL KINDS OF POWERS
THEY JUST NEED
A LITTLE MORE

The of them jump and fly and crash against each other.

The song continues PRACTICE!
IF YOU'RE A FUTURE HERO
COME AND YOU WILL SEE
YOU BELONG
AT HERO ELEMENTARY
WE ALL BELONG
AT HERO ELEMENTARY

The name of the show reads "Hero Elementary."
AT HERO ELEMENTARY

Mister Sparks says IT WAS AN ORDINARY,
QUIET MORNING
IN CITY TOWN.
BUT AT THE HOME
OF DR. INVENTORMAN,
THE FAMOUS HERO-INVENTOR,
TROUBLE WAS ABOUT
TO SPROUT UP.
(GASPS)

Doctor Inventorman says AT LAST,
I'VE FINALLY INVENTED...
THE TURBO GROWER!
NOW TO TEST IT OUT THIS SEED.
OKAY, YES, YES, YES.

He plants the seed and says NOW--MM-HMM, OKAY.
WE'LL JUST TAKE THAT
AND PUT IT OVER HERE.

(music plays)

He points the beam at the plant pot and says TURBO GROW!

(music plays)

The seed morphs into a fully grown plant.

(LAUGHS)

Doctor Inventorman says IT'S WORKS!
(LAUGHING)
IT WORKS, IT WORKS, IT WORKS!
HMM.
HMM...HMM...
(WHISPERS)

He points the beam at his hair and says TURBO GROW!

(music plays)

Doctor Inventorman says AH!
OOH!
YOU'RE BEAUTIFUL,
LOOK AT YOU!
(ALARM BLARES)

Doctor Inventorman says OH, SOMEONE IS IN NEED
OF AN INVENTION!
I MUST GO!
(DRAMATIC MUSIC)

(music plays)

He puts on his lab coat, draws his ceiling open and says INVENTORMAN AWAY!

(music plays)
(SUSPENSEFUL MUSIC)

As he flies away, a coat rack falls on the turbo grow and it shoots the beam at the plant. The plant grows huge

(music plays)

Mister Sparks says MEANWHILE,
AT HERO ELEMENTARY...
MY CLASS WAS A BIT TIED UP
WITH HERO TRAINING.

Sara says MR. S,
REMIND ME WHY WE'RE PRACTICING

Mister Sparks says WITH THESE ROPES?
WELL, SOMETIMES
A HERO COMES TO THE RESCUE
BY CLIMBING OR SWINGING IN,
SO TODAY WE TRAIN!

Sara says GOT IT!
I'LL CLIMB TO THE TOP
IN NO TIME!
(GRUNTS)

With her super strength, she rips the rope off the ceiling.

She says WHOA!
OOPS, TOO STRONG.

Mister Sparks says WELL, RESCUES DON'T
ALWAYS GO AS PLANNED.
BUT YOU'RE NOT GIVING UP,
ARE YOU?

Sara says NEVER!
I'LL says STILL GET TO THE TOP!
(WHOOSHES)

She snaps her fingers and pops up on another rope.

Sara says SEE? THIS WAS WAY EASIER
THAN CLIMBING.
(ALARMS BLARING)

Sara says HUH? WHAT'S GOING ON?
(CAR HORNS HONKING)

Lucita says COME ON, TEAM!
LET'S GO SEE!
(ENERGETIC MUSIC)

A.J. says AHH!

(music plays)

A.J. says WHAT'S GOING ON?
AHH!

Sara says WHOA!
(DRAMATIC MUSIC)

(music plays)

Benny says OH, IT'S A GIANT PLANT!
UH, AND IT'S GROWING
OUT OF CONTROL!

A scared Emoji bubble pops out of Fur Blur's head.

(SQUEAKS)

Lucita says WE'VE GOTTA DO SOMETHING!

Mister Sparks says WELL, WHO'S THE CREW
WHO KNOWS WHAT TO DO?
(TRIUMPHANT MUSIC)

They all say SPARKS' CREW
TO THE RESCUE!

(music plays)
(CAR HORNS HONKING)

The plant is growing its vines all over the city.

(music plays)

Mister Sparks says OH, DEAR.
WHOA!
(WHOOSHES)
OOF!
(GASPS)

Lucita says I'VE NEVER SEEN A PLANT
GROW THIS FAST BEFORE!

Benny says YEAH, IT JUST KEEP GROWING...
AND says GLOWING!
(SQUEAKS)

Benny says IT COULD TAKE OVER THE CITY.

Sara says WILL IT EVER STOP?

(music plays)

Suddenly at the lab, one of the vines turns the turbo grow switch off.

(MACHINE SPINS DOWN)

Sara says OH, LOOK.
IT STOPPED.
SO, PROBLEM SOLVED.

Lucita says BUT THIS PLANT
IS IN EVERYBODY'S WAY.
IT'S says STILL A BIG PROBLEM.
(TRAIN CLATTERS)
(CAR HORNS HONKING)

Benny says WE MUST RID OUR FAIR CITY
OF THIS PESKY PLANT!

Lucita and A.J. say HUH?

Benny says YOU KNOW, GET IT OUT OF HERE.

A.J. says BUT HOW?

Lucita says OOH, WE CAN USE OUR...

They all say SUPERPOWERS OF SCIENCE!

Lucita says OKAY.
LET'S START BY INVESTIGATING
TO FIND OUT MORE
ABOUT THIS PLANT.
LET'S GO!

Benny says WELL, THE FIRST THING
I NOTICE IS,
THIS PLANT IS HUGE!
(WHOOSHES)

Sara says YEP, AND IT'S GOT
DIFFERENT PARTS,
LIKE THIS GIGANTO STEM
THAT'S BLOCKING EVERYTHING.
(SOFT MUSIC)

Lucita says AND THESE BIG LEAVES
THAT ARE REALLY IN THE WAY!

Sara says I'M GOING TO INVESTIGATE
MORE FROM THE AIR.

Fur blur chomps on a leaf and spits it out. A disgust Emoji pops out of his head.

Benny says I'LL BUBBLE UP
FOR A LOOK TOO!
(WHOOSHES)

Mister Sparks says ALL RIGHT.
WHAT ELSE CAN WE DISCOVER
FRO DOWN HERE?

A.J. says HMM, I NOTICED THAT
SOME OF THE PLANT
IS TWISTE AROUND
AND says AROUND THINGS.

Mister Sparks says THAT COULD MAKE IT HARD
TO GET IT OFF.

A.J. says OOH, I MIGHT HAVE
A GADGET THAT COUL HELP.
I THINK IT'S IN HERE.

Sara says DON'T WORRY, I GOT THIS.
(WHOOSHES)
(WHOOSHES)

Sara says A LITTLE SUPER-STRETCH
SHOULD DO THE TRICK.
(GRUNTS)

A.J. shoots his gadget at one of the stems.

Sara says HUH? WHOA!

Mister Sparks says OOH, WHAT IS THAT GADGET, AJ?

A.J. says I CALL IT TWISTER RESISTOR.
I INVENTED IT MYSELF.
IT CAN UNTWIST ANYTHING!
(GADGET WHIRRING)

Sara says WOW!

A.J. says SEE?
(LAUGHS)

Mister Sparks says INCREÍBLE!

Sara says COME ON, AJ,
LET'S UNTWIST THIS TOWN!

Mister Sparks says THINGS WERE LOOKING UP,
AND SO WAS LUCITA.
(GULPS) DON'T LOOK DOWN.

Lucita says DON'T WANT TO GET DIZZY.
OH!

Benny says LUCITA, DO YOU NOTICE
HOW THIS PLANT...
GREW UP THESE BUILDINGS?

Lucita says YEAH, I DID NOTICE THAT.
I WONDER WHY.

Benny says WHOA! COME WITH ME!
WHOA!
SEE HOW DOWN HERE
IT'S DARKER AND SHADY?
BUT UP HERE
IT'S BRIGHT AND SUNNY!

Lucita says SO MAYBE THE PLANT
WAS GROWING UP
TO GET TO THE SUNLIGHT
BECAUSE PLANTS NEED THE SUN!

Benny says HEY, A PLANT'S GOTTA DO
WHAT A PLANT'S GOTTA DO.

A.J. shoots his untwisting beam and Lucita and Benny fall down.

They say AH!
WHOA!

Sara says OKAY, THE PLANT IS UNTWISTED.
NOW I CAN SAY PROBLEM SOLVED.

Lucita says BUT IT'S STILL EVERYWHERE,
ANDIN EVERYBODY'S WAY.
(CAR HORNS HONKING)

A.J. says HMM. WHAT DO WE DO
WITH THE PLANT NOW?

Benny says I DON'T KNOW.
PLANTS DON'T USUALLY GROW
THIS BIG OR THIS FAST.

Sara says I WONDER WHY THIS ONE DID.

Mister Sparks says HOW CAN WE FIND OUT?

Lucita says WE KEEP INVESTIGATING.
MAYBE IT WOULD HELP
IF WE CAN FIGURE OUT
WHERE THIS PLANT
STARTED GROWING.

A.J. says YES! WE CAN FOLLOW
THE PLANTS says STEM.
THAT SHOULD LEADS US RIGHT BACK
TO WHERE IT STARTED.

Mister Sparks says AND SO
MY HERO STUDENTS FOLLOWED
THE TWISTS says AND TURNS
OF THE PLANTS GIANT STEM
ALL THE WAY BACK TO THE ROOT
OF THE PROBLEM.
(ALL GASP)

Benny says OVER THERE!
THE PLANT IS COMING
FROM INSIDE THIS HOUSE.

Lucita says SO THAT MEANS THE PLANT
BELONGSTO SOMEBODY.
THEY SHOULD BE THE ONES
TO DECIDE WHAT TO DO WITH IT.

A.J. says HMM. WHERE HAVE I SEEN
THIS HOUSE BEFORE?

Lucita says HEY TEAM, I DON'T THINK
THE PLANT'S
LOOKING VERY GOOD ANYMORE.

Benny says BUT THERE'S PLENTY
OF SUNLIGHT HERE,
SO IT'S GETTING WHAT IT NEEDS.

Lucita says STILL, SOME OF THE LEAVES ARE
GETTING BROWN AND DRIED OUT.

A.J. says WE CAN'T LET ANYTHING BAD
HAPPEN TO IT.
THIS IS A SPECIAL PLANT.
IT'S GROWN BIGGER AND FASTER
THAN ANY PLANT WE'VE EVER SEEN!

Sara says YEAH,
MAYBE WE SHOULD HELP IT,
UNTIL ITS OWNER GETS BACK.

Benny says YES! WE SHALL SAVE THE PLANT!
UH, WHAT DO WE DO?

A.J. says HMM.
THOUGHT PROJECTING!
MY MOTHER WATERS HER
HOUSEPLANTS WHEN THEY'RE DRY.
MAYBE THIS PLANT
NEEDS WATER TOO.

Benny says I BET A PLANT THIS BIG
WOULD NEED LOTS OF WATER.

Sara says LOTS OF WATER COMING UP.
(WHOOSHES)

She pops up with a water can and says HAH! AHA.

Benny says UM, I DON'T THINK
THAT'S ENOUGH.

A.J. says BESIDES, WHEN MY MOTHER
WATERS says HER PLANTS,
SHE POURS THE WATER ONTO
THE DIRT THEY'RE PLANTED IN.

Lucita says SO WE SHOULD WATER THE DIRT
THAT THIS IS PLANTED IN.

Sara says THAT COULD BE A PROBLEM.
THE POT IS BROKEN,
AND says THE DIRT FELL OUT.
AND NOW THERE ARE ALL THESE
LONG, ROPEY THINGS IN THE WAY.
WAIT...

A.J. says I KNOW WHAT THOSE ARE.
THE PLANT'S ROOTS!
I'VE SEEN THEM
WHEN MY MOTHER MOVES
A PLANT INTO A BIGGER POT.
AND THEN SHE COVERS
THE ROOTS WITH DIRT.

Sara says SO THE PLANT'S ROOTS
ARE UNDER THE DIRT?

A.J. says RIGHT. AND THEN MY MOM
POURS WATER ON THE DIRT.

Lucita says SO THEN THE WATER MUST SOAK
INTO THE DIRT,
WHERE THE ROOTSARE.

Benny says THAT MUST BE HOW THE PLANT
GETS ITS WATER.

Mister Sparks says FANTASTICO! I LIKE HOW
YOU FIGURE THAT OUT TOGETHER!

Sara says OKAY, BUT WE STILL DON'T KNOW
HOW WE'RE GOING TO WATER
THAT PLANT,
WITH THE POT BROKEN AND ALL.

Mister Sparks says AND BESIDES,
THIS IS NOT OUR HOUSE.
WE WOULD NEEDo PERMISSION
TO GO INSIDE.

Lucita says HMM. I WONDER WHOSE HOUSE
THIS IS ANYWAY.
(WHOOSHING OVERHEAD)

Doctor Inventorman comes back home.

(DRAMATIC MUSIC)

He says WHA...? I DON'T BELIEVE
WHAT I'M SEEING!

A.J. says NEITHER DO I!

He whispers in Lucita's ear DO YOU KNOW WHO THAT IS?
AWW.
(BACKPACK CHIRPS)

He takes out a magazine from his backpack and THAT'S DR. INVENTORMAN,
THE HERO-INVENTOR!
OH, I KNEW THIS HOUSE
LOOKED FAMILIAR!

Doctor Inventorman says WHAT IS GOING ON?

Mister Sparks says THESE YOUNG HEROES
HAVE COME TO HELP.

Sara says YEAH, YOUR PLANT GREW
OUT OF CONTROL SUPER FAST.
BUT WE DON'T KNOW WHY.
(GASPS)

Doctor Inventorman says WHERE'S MY TURBO GROWER?
OH NO!
NO!

A.J. says OH,
SO THAT'S WHY IT GREW SO FAST.

Doctor Inventorman says HOW AM I EVER GOING
TO UNTWIST IT?

Sara says AA.J. says INVENTS THINGS TOO,
AND HE HAS A GADGET
THAT CAN HELP.
(QUIETLY)

Lucita says USE YOUR TWISTER RESISTOR.

A.J. says OKAY...
(BACKPACK CHIRPS)
(CHUCKLES NERVOUSLY)

He untwists all the stems with the beam.

(GADGET WHIRRING)

Doctor Inventorman says VERY IMPRESSIVE!
IT'S, UH, NICE TO KNOW
THERE ARE HEROIC,
YOUNG INVENTORS LIKE YOU.

A.J. gasps and says DR. INVENTORMAN,
I'VE READ ALL YOUR COMIC BOOKS
AND SEEN
YOUR ENTIRE MOVIE TRILOGY
AND STREAMING TV SERIES.
ALTHOUGH YOUR HAIR
LOOKS THICKER IN PERSON.

Doctor Inventorman says YOU NOTICED?
HUH.
(LAUGHS)
SO HOW DID YOU KNOW THE PLANT
STARTED HERE AT MY HOUSE?

A.J. says WE INVESTIGATED AND FOLLOWED
THE PLANT'S STEM HERE.

Doctor Inventorman says AH! YOU USED THE SUPERPOWERS
OF SCIENCE!

A.J. says YOU KNOW ABOUT THOSE?

Doctor Inventorman says OH, OF COURSE!
WE GROWN-UP HEROES
USE THEM ALL THE TIME.

A.J. says WELL, SCIENCE DOES GIVE US
THE BEST SUPERPOWERS!

Doctor Inventorman says BUT NOW I'VE GOT A PROBLEM.
THIS PLANT IS MUCH TOO BIG
FOR MY HOUSE.

A.J. says HMM.
WHEN MY MOM'S PLANTS
GET TOO BIG,
SHE PLANTS IT OUTSIDE.

Sara says MAYBE WE CAN MOVE THIS PLANT.

Lucita says YEAH. SOMEWHERE IT CAN GET
PLENTY OF WHAT IT NEEDS.

Benny says LIKE LOTS OF SUNLIGHT
AND DIRT AND WATER!

Mister Sparks says SO WHERE CAN A PLANT THIS BIG
GET ENOUGH OF ALL THAT?

Sara says I THINK I KNOW
JUST THE SPOT FOR IT.

(music plays)

They plant it at the park.

Sara hangs from one of the stems and says WHOA-HO-HO!
THIS IS MORE LIKE IT!

Mister Sparks says WELL, CLASS, OUR PLANT
LOOKS VERY HEALTHY, YES?

Benny says THE LEAVES AND STEM
LOOK STUPENDOUS!

A.J. says AND THE ROOTS ARE
SAFELY COVERED IN THE DIRT.

Lucita says THIS IS THE PERFECT PLACE
FOR IT.
YIPPEE! (LAUGHS)
(SQUEAKING IN DELIGHT)

Mister Sparks says AND MY STUDENTS DISCOVERED
THAT A PLANT'S PARTS
HELP IT GROW,
GET SUN AND WATER,
AND,
IF IT'S A SUPER-BIG PLANT,
CAN EVEN HELP
WITH HERO TRAINING!

They all sing WE ALL BELONG
AT HERO ELEMENTARY
(SHOW THEME MUSIC)

Music plays as the end credits roll.
