[Bouncy music plays]

One red block with eyes has the number one over it. Beside it runs Two’ a stack of two orange blocks; Three, a stack of three yellow blocks; Four, a square made of four green blocks; and Five, a stack of five blue blocks.

Voices sing, ONE, TWO, THREE, FOUR, FIVE,
NUMBERBLOCKS

Six, two columns of three blocks, jumps into the air. Seven, a stack of seven different coloured blocks; Eight, two columns of four blocks; Nine, three columns of three blocks; and Ten, a stack of ten white blocks outlined in red; jump into the air.

Voices sing, SIX, SEVEN, EIGHT, NINE, TEN,
NUMBERBLOCKS

ONE AND ANOTHER ONE IS TWO
AND ANOTHER ONE IS ME
THAT'S THREE
FIVE, FOUR, THREE, TWO, ONE,
TIME FOR SOME NUMBER FUN

YOU CAN COUNT ON US,
WE'RE THE NUMBERBLOCKS

[Electronic music plays]

[Cheering]

Number blocks slide along bright rays of light.

Fourteen says, TWO BY SEVEN, EXTREME!

Number stacks combine on the ray below, counting as they increase.

Three says, THREE!

Six says, SIX!

Nine says, NINE!

Twelve says, TWELVE!

Fifteen says, FIFTEEN!

Eighteen says, EIGHTEEN MAKES THE SCENE, YOU THINK
THIS IS FAST?
FOLLOW ME FOR SOME REAL SPEED!

[Whoosh]

All of the number blocks jump up to the single red ray at the top.

[Cheering and laughing]

Eighteen asks, ARE YOU FAST ENOUGH TO LOOP THE LOOP?
GO, GO, GO!

The number slide along a loop.

[Cheering]

Fourteen says, AWESOME

Fourteen breaks into two seven blocks.

As the sevens land, they say, LET'S DO IT AGAIN!

[Cheering]

Eighteen says, HA! ANYONE CAN RIDE THAT THING.
CHECK THIS OUT.

Eighteen gestures to a double loop.

[Music chimes]

Fourteen, Sixteen and Twelve say, WHOA!

Eighteen says, THE DOUBLE LOOPER HAS A
TWO RAY, MATEYS!
SO YOU CAN ONLY RIDE IT IF YOU
CAN MAKE A RECTANGLE THAT'S TWO
BLOCKS WIDE!
LIKE THIS.

Eighteen shifts into two tall nine stacks of blocks.

TWO BY NINE.

TWO RAYS, AND AWAY!

Eighteen slides on the loop.

Eighteen says, ONE, TWO, WHOO-HOO!

Twelve turns into two stacks of six blocks.

Twelve says, AND TWO BY SIX! WHOA!

Fourteen shifts into two tall blocks of seven.

Fourteen says, TWO BY SEVEN!

Two sevens shout, DOUBLE LUCKY DOUBLE SEVEN!

Sixteen says, TWO BY EIGHT!

Twelve, Fourteen and Sixteen slide on the loop.

[Cheering]

[Sigh]

Fifteen says, THAT DOES LOOK LIKE FUN, BUT
ODD NUMBERS LIKE ME CAN'T MAKE A
RECTANGLE TWO BLOCKS WIDE.
SEE?

Eighteen says, DON'T LET THAT SLOW YOU DOWN,
FIFTEEN, THIS NEXT ONE COULD BE MADE FOR YOU.

Three rays form a yellow triple loop.

Fifteen says, A TRIPLE LOOPER WITH
THREE RAYS?!

Eighteen says, SO YOU NEED TO MAKE A
RECTANGLE THAT'S THREE BLOCKS
WIDE, LIKE THIS!
THREE BY SIX!

[Electronic music plays]

Eighteen slides along the loops.

Eighteen says, THREE RAYS AND AWAY!
THREE BY SIX,
WHOO-HOO, DONE AGAIN!

Fifteen says, NOW THAT I CAN DO.
THREE BY FIVE!

[Laughter]

Fifteen yells, THREE BY FIVE!

Eighteen says, WHOA!

Fifteen says, AMAZING!
YOU'RE BUILD FOR SPEED, EIGHTEEN.

Eighteen agrees, MM-HM.

Fifteen says, YOU CAN RIDE LOOPERS, AND
DOUBLE LOOPERS, AND TRIPLE
LOOPERS!

Twelve slides and says, THREE BY FOUR!

Twelve lands beside Eighteen.

Twelve says, AH, THAT'S BECAUSE MY BROTHER
AND I ARE BOTH SUPER RECTANGLES!

Eighteen says, WHICH MEANS WE CAN MAKE LOTS
OF DIFFERENT RECTANGLES.

Twelve and Eighteen transform into different shapes.

Eighteen says, SO WE CAN MAKE ONE RAYS!

Twelve says, AND TWO RAYS!

Eighteen says, AND THREE RAYS!
AND THAT'S NOT ALL.
WE CAN BOTH MAKE SIX RAYS!
SIX BY THREE!

{Twelve chuckles]

Twelve says, WELL, YES, THAT'S TRUE.
SIX BY TWO.
BUT WHY DO WE NEED SIX RAYS?

[Gasp]

Twelve continues, UNLESS...

Six purple rays form six loops.

Twelve and Eighteen say, THERE'S A SIX LOOPER!

[Disappointed music plays]

Eighteen says, OH NO, HOW DO WE GET UP
THERE?!

[Chuckling]

Twelve says, RELAX, LET ME HANDLE THIS.
I AM TWELVE.
I AM A SUPER RECTANGLE.
MASTER OF THE RAYS.

[Humming]

Twelve points and the start of the looping rays lowers to Eighteen.

Eighteen says, OH!
OH, WAIT, CAN YOU DO THAT AGAIN?

[Majestic music plays]

BEHOLD THE SUPER DUPER
LOOPER!

All of the looping rays are lined up in a row.

Eighteen says, G-G-G-GO!

Twelve says, SWITCH!

Eighteen says, ONE BY EIGHTEEN!

[Electronic music plays]

Twelve says, ONE BY TWELVE!

Eighteen switches and says, TWO BY NINE!

Twelve says, SWITCH!
TWO BY SIX!
WHOA!

Twelve and Eighteen slide on the double looper.

[Cheering]

Twelve calls, SWITCH!
THREE BY FOUR!

Eighteen says, FAST WORK, SIS!
RACE ON!
THREE BY SIX!
WHOO-HOO!

[Both cheer]

Eighteen says, SIX BY THREE, SEE YA!

Twelve says, SWITCH!
SIX BY TWO!
WHOA!

They slide along the six looper.

[Both shout and cheer]

Twelve says, PHEW, THAT'S FAST ENOUGH FOR ME!

Twelve shifts into block of twelve ones. Ten parachutes open and slow her fall.

Eighteen says, BUT NOT ME.
HERE COMES THE NINE LOOPER!

A glowing white spiral leads downwards.

Eighteen says, NINE BY TWO, COMING THROUGH!
WHOA, WHOA, WHOA, WHOA, WHOA!

[Whoosh]

[Shouting]

Fourteen says, EXTREME, DUDE!
ARE YOU OKAY?

Eighteen says, THAT WAS REFRESHING!
AND NOW TO DO SOMETHING ELSE
REALLY FAST.

Eighteen falls over.

Eighteen says, AH...HAVE A LIE DOWN.

[Laughter]

Twelve says, OH, EIGHTEEN.
