  • Kirby (Racing with "Popstar on Wheels") Pit crew: Waddle Dees

  • Mr. P appearing in this episode is actually a continuity error, since he would technically be back to normal after the events of IaLR.
  • Galaximus warns the gang that they will fight her someday. This is another continuity error, since the gang already escaped the rooms long ago.


  • Mario Kart 8/Mario Kart 8 Deluxe - The whole episode is based off the game.
  • Club Penguin and Club Penguin Island - RPSN is a reference to CPSN, a fictional sports network that covered the Penguin Cup, and is set to appear in the upcoming Mt. Blizzard area. In addition, Aunt Arctic and Rookie appear as reporters for the network.
  • Sonic the Hedgehog/Super Smash Bros. Brawl - Papyrus references both of Sonic's quotes in the game Super Smash Bros Brawl. in one sentence. These quotes are from where Sonic taunts. Papyrus says: "Step it up, Sans! See! I told you you'll be too slow!" Sonic's quotes are: "You're too slow!" and "Come on, step it up!"
  • Various RPG games - Neptune referenced the experience points the RPG games use, by mentioning what it leads to - leveling up. She said: "Next! I'm gonna level up so much!"


  • The original name for this was "Rainbow Road 2000".
  • There was originally going to be an 'Invent -Off' subplot, but it was scrapped while this episode was ongoing.
  • The title of this episode is named after a song by LONELYROLLINGSTARS, a cover of MKDD's Rainbow Road called "Royal Rainbow Road".
    • Coincidentally, the part of the name "Royal Rainbow" references the Katamari series.
  • This is one of the few non-special episodes in which the gang is actually outside the rooms, since this actually takes place after IaLR.
  • This is the only episode after The Room of Terraria to not feature Lucas.
  • The Cursed Shroomers from Season 1 make their return in the subplot, but only the 50th one is going to be featured for now. In addition, their alignment has been changed.
  • This has the most flashback characters to appear in one episode.
    • This also has the most guest characters of DJayKn1ght's to appear in one episode.
