It is theorised that when the designs of K and S were changed, C needed to be changed as well to counteract K because her design seemed too pointless now that K and S were both revised. The patterns that One Hundred does are beyond impossible to do in the sketch, although it was a rough sketch. The magic mirror that Twenty-One uses was originally going to be on the wall, covered in moss. This was changed so that the Ones in the mirror can get out. G's flower was split into 2 flowers that appear on the sides of G's body, and was given grass hair. This episode was listed as episode 14, when it is actually episode 12, and that the actual episode 14 is "Holes".

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. 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. Speaking of G, she was originally going to represent "green", until they decided that G was better off with H's old personality. 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.

This episode was listed as episode 20, when it is actually episode 19, and that the actual episode 20 is "Ten". This was before the event which split Season 1 (containing both "High Five" and "Ten out of Ten") into their own separate seasons. If this was always the case, the episode would be coded as "NUM_204_NIN" instead. Like above, Nine's colours are different but it was to make him easier to animate since he is completely made of greys. Yellow always kept his happy personality in the series, but the second and third shown him as a female.

M's legs and feet were changed from grey to blue. The reason for this is unknown, probably to make him slightly more colourful.

Red’s first and second designs were male, and the first design depicted Red as an angry person, as red is the colour of anger.

The music that plays during the Jump and Bump in the storyboard video only consists of small percussion, kind of like a metronome. It's likely that the song wasn't finalised. Sevens are present when Seventy splits into Sevens, instead of the acceptable 10. The Sevens' colours are also upside down. So many blue characters have had their colours changed, since there were too many blues, and the colours had to be diverse. The final design of Z is essentially the second, purple Z but without the orange robe and is coloured like the other two Z's that aren't the superhero one.

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. Ten Thousand's eyes are round rather than square in the storyboard, despite being a square number. Same thing with One Million. Originally, the episode was going to take place at daytime instead of at the sunset like in the final version.
