Seventeen and Three seem to have a good relationship but it's probably the first time Numberblocks which aren't alter-egos hate each other; Three hates Seventeen at first, due to how much times she gets used and abused. Later through out the episode she starts suffering from insanity.


  • Stikbot1992's design of 17 is his favourite design so far.
  • It was confirmed on Twitter that 17 is male.
  • While some Numberblocks were based off of other things (like 8 being based off of octopuses/the infinity sign which is commonly used for heroes, 6 being off of a dice and 12 being based on arrays), 17 is instead based off of painting rather than being a ninja/haiku maker, which some people expected. This is because ninjas are frowned upon in the UK, and the fact that Seven is rainbow-coloured.
