Trivia
This is the first short that Motsuki appears in.
This is the second time one of the PJ Masks is alone in their HQ.
Luna Girl telling Gekko that he had done babysitting before possibly mentioned "Terrible Two-Some."
This implies that Luna was presumably spying on Gekko while he was babysitting Kitten Boy and Chicklette during the events of the aforementioned episode.
Motsuki is the second villain to be invited into the PJ Masks HQ.
