Sixty-Three, or 63, is a Numberblock made of 63 blocks.

Appearance

Sixty-Three has 60 lavender blocks with indigo borders, and 3 yellow blocks. He has yellow rectangle eyes and a pink mouth with teeth similar to Four or Forty. He has a rainbow headband with a grey rainbow on it to show that he is 7 times 9. As seen in Nine's Time to Shine, he has yellow eyebrows. He has yellow limbs, light yellow shorts, and an array display as he has 6 factors.

The nine Sevens he splits into are all grey, three light, three medium, and three dark. Their faces, limbs, and hair are also grey, and they can make grey rainbows. His seven Nines remain the same, but their center blocks have seven different colors of the rainbow with one colour each and are able to sneeze confetti in the seven colours of the rainbow.

Personality

Sixty-Three is part of the Rainbow Sevens, and he loves that too, but he never likes making grey rainbows at all because all their colour is lost, likewise to Nine. Though he detests grey-coloured rainbows, the others like it, making him proud of it now.

He also has seven nines with their centered blocks (noses) a colour each in the rainbow. They can sneeze confetti out of their noses in their given nose colour, just like what happened in The Rainbow Makers, when Fifty-Six suggested his to turn himself around, he made 7 nines with rainbow middle blocks that sneezed confetti out, Sixty-Three liked it.

Errors

In his tens and ones arrangement in Nine's Time to Shine, he is shown with eyebrows. It is unknown whether it is an error or his eyebrows are covered by the headband, but in Sail the Seven Seas, on the sideways part, Sixty-Three has his face in the centre with his headband on the top with no eyebrows, so maybe it was an error.
