The scoreboard in the storyboard goes from 60, scrolls through from 61-69 and stops at 70 rather than going straight from 60 to 70 in the final cut. Q was originally going to be bald, and appeared quite young. It was possible that Q was originally a male character. This has some issues (Q was too basic, and there were more males than females at the time.) He had to be aged up, and had to be changed to a female so that the gender ratio will be balanced. H's old design was what later became of G, since it contrasts with her exercises. However, this trait was later given to G since she made more sense with growing plants with water than H did. H then became more relevant to exercising. F originally had a pink ribbon around her, until it was replaced by a spacesuit. It is unknown what purpose F would have had before she underwent changes, but it’s likely she would’ve been a ballet dancer.

P gained the green and purple colours, forming a gradient of green, blue and purple. You can still see "seafoam" as a colour on P.Eight looked much brighter than he is in the show, he only has 4 limbs, and his face was smaller. His square with a hole shape was not implemented to the episode yet, which is why he appears in his 2x4 rectangle shape when Nine sneezes. Two of the Fours from Forty are next to each other in the storyboard when they lift the tent up, although they aren't in the final product. In the Spanish dub, when the Ones were adding up, the compound Twenty-One’s voice only had Twenty’s voice heard.

This episode was listed as episode 14, when it is actually episode 12, and that the actual episode 14 is "Holes".

Like above, Nine's colours are different but it was to make him easier to animate since he is completely made of greys.

Ten Thousand's eyes are round rather than square in the storyboard, despite being a square number. Same thing with One Million.

So many blue characters have had their colours changed, since there were too many blues, and the colours had to be diverse. The fourth Z is much, much different to the other three Z's. He looked like a superhero like X, is pink with a yellow lightning bolt on his face and has white gloves and pink boots. It is unknown if this Z is male like all the other Z's, or is female.
