This page is about the Numberblocks character. For the Numberblocks episode, see Four (Numberblocks episode). For the Alphablocks episode, see Four (Alphablocks episode).

Four, or 4, is the Numberblock made up of 4 lime green blocks. His favorite shape to be is a square.

Four first appeared in the episode with the same name.

He is voiced by Marcel McCalla.


Four is most strongly defined by his very shape. He loves squares and loves being a square. He likes being in the company of other squares, as he's always seen in Square Club whenever it's in an episode. In contrast, he has a fear of round things, avoiding touching them as much as possible. This makes it hard for him to enjoy ball games such as football. Like other squares, he's very strong. He doesn't shy away from showing this, taking many opportunities to help lift heavy things. In some episodes/images, he can be seen flexing his arms.

He owns a pet square named Squarey.

When he struggles to decide between two choices, he splits into the Terrible Twos.


Total number of appearances: 110 + 2 (Incl. pictures)


Big Bad Square

The Big Bad Square is the alter-ego of Numberblock Four that appears in the episode "Three Little Pigs".

Costume Appearance

The Big Bad Square's costume is a wolf disguise consisting of ears, a nose, and a tail.


The Big Bad Square's role is the same as the Big Bad Wolf in the original Three Little Pigs story. He comes up to each house saying "Little pig, let me in!" Whenever a Numberblock 1, 2, or 3, denies by the hair on one's chin, Four says, "And I'll huff and I'll puff and I'll blow your house in!" So he blows down the houses and the Numberblocks out of the house.

As Three wonders where the pigs will live now, Four shows the pigs his house, which is green with four rooms, four square windows, four trees, and a number 4 on the door. The pigs now live with the Big Bad Square.

The Terrible Twos

The Terrible Twos are the evil twos; one wears a purple mask and the other wears a blue mask. They appear in The Terrible Twos, Peekaboo, Octoblock to the Rescue!, Mirror, Mirror, Square Club, Terrible Twosday, and Now in 3D.


Four can be arranged vertically or in a square. He can also be horizontal, L/J-shaped, S/Z-shaped, Bolt-shaped, or T-shaped.
