Appearance
12 has 10 white blocks and 2 orange blocks. She has also thin eyebrows, rectangular eyes, red limbs like 10, and has a pink thing on her wrist called her "array display" on her left hand, which looks like a rectangular watch. She is often arranged in a rectangle, which is her favorite shape.
When 12 is in her 3by4 or 4by3 form, her 2 orange blocks are in the middle and 10 white blocks at the outside (a tall donut or a rectangle with a hole, 2 has said the second one on 12‘s debut episode). She first appears in her 3by4 form.
When 12 is in her 2by6 or 1by12 form, her 2 orange blocks are on the 10 white blocks.
When 12 is in her 6by2 or 12by1 form, her 2 orange blocks are next to the 10 white blocks. In her 6by2 form, her 2 orange blocks can be either on the left or right of the 10 white blocks, but in her 12by1 form, they can just be on the right.
