Block Star is an episode of Numberblocks Season 4.


Twelve goes on a mission to save Numberland from the mysterious Block Star.


Twelve is flying through space, heading for the Block Star. One warns her that the Block Star is running out of battery and it needs to be changed before it falls and crashes onto Numberland. She becomes a team of two Sixes, three Fours, four Threes, six Twos, and twelve Ones.

Twelve needs to turn off the force field before she gets to the battery. She sees a line of six towers ahead, each having two buttons on top, which all must be pressed simultaneously. Array display.

12 = 6 x 2

Twelve separates into six Twos. They all press the buttons with their feet at the same time, turning off the force field.

Twelve sees a wall with four holes, each being three blocks tall.

Twelve separates into four Threes. They all fit through the holes.

The Battery Power is 20%.

Twelve sees a pair of block drone ships going haywire due to the low battery. Array display.

12 = 2 x 6

Twelve separates into two Sixes. They demand a game of hide-and-seek. They hide from the six block ships where they can't make them lose. Unfortunately, six more block ships are chasing Twelve.

Twelve sees a gate closing slowly. Above it are the numbers 1-12. Array display.

12 = 12 x 1

The gate deploys 11 lasers between block-sized gaps. Twelve separates into twelve Ones. They all pass through the twelve holes. The block ships bump onto the closed gate.

  • 0 , 10 and 11 are absent in this episode.
    • Coincidentally, 10 and 11 are two-digit numbers.
  • The block ships were assumed haywire due to low battery. Additionally, their color is determined by the number they are grouped in.
  • The battery, depending on the status, shows its percentage divided by 10’s color. For example, if 70%, it shows 7's rainbow colors.
  • 2, 3, 4 and 6 are the only Numberblocks in this episode to appear when split or divided from 12 (If you count 1 since she is in the lab with 5, 7, 8 and 9 and can appear when split by 12 during the episode).


  • The Block Star is based on the Death Star from Star Wars.
  • When Twelve says “Use the Fours!”, it is a reference to the Star Wars quote “Use the Force.”
  • Additionally, Twelve says "I've got a bad feeling about this." This is actually a quote throughout the Star Wars saga.
  • The scene with the four Threes flying through their hole is similar to the game show Hole In The Wall.
  • When the Disco Cube shows on screen, it is a stealth reference to cube numbers, as it is a 2x2x2 cube.


  • Even though the 4 Threes say "LOOOOK AAATT MEEEEEEEEEE!", the subtitles read "Whoo, catch me!!!!"
