  • Song: Born To Ride The Rays
  • This episode has the most fourth wall breaks in the whole Numberblocks and Alphablocks world.
  • There's a blurry version of Ray Canyon and the HQ from Block Star when 18 flies fast as his vertical form; apparently, Ray Canyon is next to Twelve's Dojo and the HQ is next to Ray Canyon.
  • This is the second time where both day and night appear; Eighteen goes so fast he ends up on the other side of the world.
  • Despite saying that he glows when he zooms, he does not glow in any other episode.
  • The only one who is shown fully unhappy from Eighteen is Five.


  • The melting ice cubes are already shown in their watery state when Eighteen gets to Block Mountain.
  • This is the first time Thirteen didn't split into Three and Ten after saying his name. The second is I Can Count to Twenty.
