(Music playing)

Animated shapes in different colours jump around an off-white background. The shapes have eyes and mouths, and arms and legs. They smile as they hop around the animated landscape, turning it into different colours.

Singing, COLOURBLOCKS, COLOURBLOCKS RED AND YELLOW AND BLUE. COLOURBLOCKS, COLOURBLOCKS. GREEN AND PURPLE AND ORANGE, TOO. IN A MAGIC WORLD OF COLOURS LOOK WHAT WE CAN DO. COLOURBLOCKS, COLOURBLOCKS WE'RE MIXING IT UP FOR YOU!

All shouting, COLOURBLOCKS!

A title reads: Colourblocks

(Giggling)

The square-shaped Blue catches a ball. One panel on the ball turns blue.

Blue says, BLUE.

Blue tosses the ball to the round Yellow.

Yellow says, YELLOW.

Another panel on the ball turns yellow.

(Laughing)

Yellow throws the ball to Blue.

Blue says, BLUE. COOL.

They toss the ball back and forth.

Yellow says, YELLOW. HA!

Blue says, BLUE.

Red, a triangular shape with a rounded bottom, runs by.

(Laughing)

Red says I'M RED.

Red spots a colourless stop sign and turns it red.

Red says, OOH. RED.

Yellow and Blue toss the now yellow and blue striped ball back and forth.

(Giggling)

Red moves the stop sign between them.

(Giggling)

Red cries, STOP!

Yellow says, HUH?

Red says, RED MEANS "STOP." WHEN YOU SEE A RED STOP SIGN LIKE THIS, YOU HAVE TO STOP.

Blue says, SO, WE HAVE TO STOP OUR GAME? NOT COOL.

Red says, OH, SORRY, FRIEND. I CAN'T HELP MYSELF. RED MEANS "STOP."

(Laughing)

Yellow says, NEVER MIND, BLUE. I'M HAPPY TO PLAY SOMETHING ELSE. OH, LOOK.

Yellow hops over to two white scooters.

SCOOTERS. YAY! YELLOW.

They put on helmets and turn the scooters yellow and blue.

Blue says, BLUE. LET'S GO.

They roll off on the scooters. They roll down a colourless hill.

Both crying, HOO-HOO-HOO!

Yellow says, WHEE!

Red jumps out with the stop sign.

Red says, RED MEANS "STOP."

Blue says, UH, NOT AGAIN.

Red says, SORRY. CAN'T STOP MYSELF.

Red runs off. Yellow and Blue turn their scooters. Red sets up another stop sign.

Red says, AND I'VE GOT LOTS OF THESE TO PUT UP TODAY.

(Giggling)

Red sticks stop signs all around.

Red says, BYE.

Yellow says, OH, DEARIE.

Blue says, HMM. TIME TO PUT A STOP TO RED'S STOPPING.

Red carries a stop sign over the colourless landscape.

(Humming)

A yellow rubber duck sits on the ground. Red jumps in front of it.

Red shouts, STOP!

Red runs off.

(Humming)

Blue tiptoes over to the sign and takes it. Red runs back and notices the duck.

(Gasping)

Red says, HMM.

Red hurries off and runs back with an armful of stop signs. Red puts the signs up around the duck.

Red says, RED, RED. RED, RED, RED.

Red runs off.

Yellow rides in on a yellow digger truck. Yellow scoops up the signs and the duck.

Yellow says, HOO-HOO-HOO!

(Duck squeaking)

Red hops around, sticking more red signs into the ground.

Red says, RED, RED. RED, RED, RED.

(Laughing)

Blue tries to grab on and stops. Yellow walks over and they stroll to a colourless tree. They sit on the ground.

Blue says, LOOKS LIKE WE CAN'T STOP RED.

(Sighing)

Yellow says, OH, WELL.

They set their hands down and touch a colourless leaf at the same time. It turns green.

Blue says, HUH? LOOK WHAT HAPPENED WHEN OUR COLOURS MIXED.

Yellow says, OH! DO YOU THINK...

Blue says, SHALL WE? BLUE AND...

Yellow says, ...YELLOW...

Both say, ...MIX TO MAKE...

Colours swirl and Green, a square shape with a rounded top, appears.

Green cries, ...GREEN!

Yellow says, YAY! I DIDN'T EXPECT THAT.

Green says, AND I DIDN'T EXPECT TO MEET OTHER COLOURS.

Blue says, SO, TELL US ABOUT GREEN.

Green says, GREEN IS A GROWING THING. NATURALLY, I LIKE NATURE. ALL OF THESE PLANTS ARE GREEN.

(Croaking)

Green says, OH, AND THIS FROG. GREEN. GREEN.

Green turns plants green. A green frog hops after Green.

(Croaking)

Red puts a sign in front of the frog.

Red says, RED MEANS "STOP."

Green says, OH, RIGHT. PLEASED TO MEET YOU. I'M GREEN.

Red says, I'M RED. AND THIS MEANS "STOP."

Green spins the stop sign around and turns one side of it green.

Green says, AND NOW IT'S GREEN, WHICH MEANS IT'S A "GO" SIGN.

(Red gasping)

Green says, GREEN MEANS "GO."

(Croaking)

Green says, GO, FROG, GO.

The frog hops away. Red and the others stare at Green.

Yellow says, UH-OH.

(Red sputtering)

Red cries, BRILLIANT! IT'S GIVEN ME AN IDEA FOR AN EXCITING NEW GAME.

(Music playing)

Blue and Yellow put on their helmets and stand on their scooters.

Green says, GREEN MEANS "GO!"

Green turns a sign green.

Yellow and Blue ride their scooters forward.

Yellow cries, HA-HA!

(Giggling)

Yellow says, YAY.

Red hops in front of them and plants a stop sign in the ground.

Red says, STOP. RED MEANS "STOP."

Blue says, OOH.

Yellow and Blue freeze.

(Giggling)

Green runs over and changes the sign.

Green says, GREEN MEANS "GO."

(Music playing)

Yellow and Blue race off.

Both say, WHEE! YAY.

Red jumps out.

Red says, HA! RED MEANS "STOP."

Blue and Yellow freeze.

Red jumps away.

Red says, HA-HA!

Green walks to the sign.

Green says, GREEN MEANS "GO, GO, GO!"

Blue and Yellow roll the scooters forward.

(Music playing)

Red jumps out and stops them. Green spins the sign around. Yellow and Blue race along a road, stopping and starting.

(Giggling)

Blue says, HUH?

(Giggling)

Green says, OH-HO-HO!

Red sets up more signs and Green changes their colours.

(Laughing)

(Giggling)
