This is the third time the PJ Masks and Kevin work together.
The first was in "The Good Wolfy," and the second was in "Romeocoaster."
This is the first time Luna Girl gives her Luna Magnet to a villain.
However, she does it to trick the Wolfy Kids.
Luna Girl introduces her backup moon crystal.
The episode reveals that the backup moon crystal is the third moon crystal.
Kevin moves his bangs for the first time.
The Wolfies don't know Luna Girl, thus allowing her to trick them into thinking she's the queen of the moon. So most likely, this episode is set before the episodes "Halloween Tricksters," "The Lizard Theft," and "Romeocoaster," in which Luna and the Wolfies already met.
On Netflix, this could be evident as this episode along with "Easter Wolfies" is listed to chronologically take place after the events of "The Wolfy Kids" and "Wolf-O-Saurus," and before the events of "Halloween Tricksters," "The Lizard Theft," and "Romeocoaster."
PJ Robot drives the Owl-Glider for the first time.
In one scene, Catboy's symbol at his chest becomes black.
