Unconfirmed trivia

  • According to Ninja Kiwi's 18th March 2022 blog, Grape Shot grapes can be occasionally eaten by Buccaneers, but not Hot Shot grapes.
  • When the Longer Range upgrade got buffed in Version 18.0, submerged Bloontonium Reactor did not receive the range buff, making it noticeably miss the top section of Firing Range. Submerge and Support remained affected by the range buff. Missing out on Reactor's range buff was likely an oversight. Tested on Version 27.3.
  • In early versions of the game, such as Version 7.x, the 2-0-4 Armor Piercing Darts would always hold its Advanced Intel binoculars upwards towards its eyes. However, in later versions the sailor will always place its binoculars on its right hand leaning on the submarine's handrails.
  • Until a certain update, 3-2-0 Fighter Plane didn't wear goggles that covered the pilot's eyes.
  • Using a Ground Zero ability and then upgrading to Tsar before the bomb lands will convert it into a Tsar ability.
  • The darts from the Spectre are 2D models, while the bombs are 3D models.
  • In BTD6, the Razor Rotors Heli Pilot will intentionally tilt towards the bloons to shred bloons. Similar behavior occurs for Apache Dartship and Apache Prime.
  • In Version 1.6 of the game, there used to be a glitch that caused the Apache Prime to be extremely powerful, firing its frontal plasma cannon at roughly five times the speed. All its projectiles seemingly did double damage as well. The cause of this glitch is unknown, as it only triggered on certain devices.
  • There was a strange interaction with Downdraft and Monkey Intelligence Bureau whereby MIB allows Downdraft to blowback Leads but not Frozen, even though Downdraft normally blowbacks neither Frozen nor Lead. As of 25.1 testing, this glitch no longer exists. Instead, Downdraft is unable to blowback Lead or Frozen Bloons completely. Frozen Bloons unfrozen are still are blown backwards if affected by at least one Downdraft effect, even after 25.1.
    • Prior to Version 36.0 reworking Downdraft's blowback effects, there was an interesting interaction with Frozen Bloons whereby the Downdraft effect can affect them only after the bloons defrost. This was discovered in Version 25.0 after Ninja Kiwi applied a damage types rework for many towers in the game. After v36.0, Frozen Bloons thaw before getting blown backwards once affected by Downdraft.

Trivia to be rewrote and added

  • "IFR" is an abbreviation for instrument flight rules.
  • It's likely an adaption of the Boeing-Sikorsky RAH-66 Commanche.
  • Formerly, the Dartling Gunner could still count as camo detection for Advanced Intel even as a base tower.[1] This was patched in Version 23.0.
  • In the Dartling Gunner trailer for BTD6, the music used is "Force Field" by Skrya, licensed by Epidemic Sound Publishing.
  • Until Version 46.0 or 47.0, Dartling's Insta images were named xxx-DartlingGunnerInstaInsta.png, but changed to remove that duplicated "Insta" word.
