The PJ Masks got their new powers from the crystal from "PJ Power Up."
Catboy claims that this is the first time they use their new powers against Romeo, which means this episode is chronologically set before "Wacky Floats."
It is revealed that there is a Romeo symbol like Catboy, Owlette, and Gekko's.
This is the first episode where the PJ Masks defeat Romeo, but he comes back in the same night.
This is the second time the Ball Cage appears in the series.
