One with her Buddy Block
A Buddy Block is a living block.
A Numberjack and his/her Buddy Blocks have the same number and color; for example, One has one purple Buddy Block. Zero is the only Numberjack who has no Buddy Blocks because he is zero - which means nothing. One, four and nine have square patterned buddy blocks as seen in square dancing. Buddy blocks can also make a mark on the paper after flying on the jump pad in the gym room, also seen in square dancing.
