Once Upon A Time is the 31st episode of Numberblocks. It is the first episode of Series 3.


If you’re sitting comfortably, then we’ll begin a bedtime story all about the first five Numberblocks.


The first scene features a book with the picture of the first five Numberblocks on the cover. The book opens up to the first page:

Chapter 1: In the Beginning

One dangles from a rope and is getting lowered slowly.

One: "Once upon a time, a red block fell from the sky."

One lands on her side, retracts her face and her limbs, and ejects them back out, but the right way up. But

"I am One! This is fun! I am One block, and this is my Numberling, it means me, ONE!"

One starts hopping around until, she knocks one of the props over. She looks at the fallen prop, mildly embarrassed, clears her throat and starts talking again.

One: But she was all alone, so she wanted to make friends. LOOK! A magic mirror! I'm one!

Another One: And I'm another ONE!

One: Anyone for tennis?!

She hits the ball, it bounces off of the top of the mirror, and bounces onto One, knocking her onto the other One.

1 + 1 = 2

Two: I am Two. How do you do?

Chapter 2: Me and You

Two: "I am Two. I have 1, 2, two blocks, and this means two. Wanna see me dance in my two dancing shoes?"

Two dances, but accidentally steps on a loose floorboard One is standing on, throwing her into the air.

2 + 1 = 3

Three: "I am Three. Look at me!"

Chapter 3: Me, Me, ME!

Three: "I am Three. I have 1, 2, 3, three blocks. I have three juggling balls, and this means three."

Three juggles her balls while One and Two watch. Two tosses One onto her.

3 + 1 = 4

Four: "I am Four. Have we met before?"

Chapter 4: Four's House

Four: "Hello, I am Four. I have 1, 2, 3, 4, four blocks. can you guess what my favorite shape is? Right, it's a square. I have 1, 2, 3, 4, four sides, and 1, 2, 3, 4, four corners."

Four sees that someone has chewed four holes on the tablecloth. That someone is his pet square, Squarey. He fixes it with four square plates.

One, Two, and Three come in the house. Four asks them who wants a square cookie. But Four cannot reach the cookie jar. One jumps on Four.

4 + 1 = 5

Five: "I am Five. I feel alive!'

Chapter 5: The Star Turn

Five: "I have 1, 2, 3, 4, 5, five blocks. And I like stars 'cause they have five points. It makes me a rock star! Thank you and good night!"

As Five ends the story, the Numberblocks 1-4 fall asleep in bed.
