At the start of the episode, Mario, while maneuvering his spaceship through a swarm of flaming meteors, mentions that he is being chased by King Koopa's Space Troopa minions; Mario evidently escaped these Space Troopas. They later appear as Moon Man Koopa's aides in the Quirk Factory.
A similar enemy appears on the moon in the NES version of Mario's Time Machine. They are identical to the Koopas found in other locations, but when knocked into their shells, the helmet covers the top of the shell instead.
A purple Koopa Troopa wearing a space helmet appears at the Moon Kingdom in Super Mario Odyssey. It hosts the Trace-Walking minigame that involves Mario walking on a circle of arrows that disappear after some time. If Mario gets 80 points, the Koopa Troopa gives him a Power Moon.
