"Who Let the Moths In?" is the first segment of the 2nd Season 4 episode of PJ Masks.


The moths infiltrate HQ, and Gekko won't admit that he let them in until it is too late.


  • The episode's title might be a reference to the song, "Who Let the Dogs Out!".
  • Luna Girl introduces her Moon Whistle in this episode, which she uses for the first time.
  • This episode, along with "PJ Sky Pirates" and "Big Sister Motsuki", is one of the post-"The Prank Wheelz" episodes to have Romeo's Lab.
  • Motsuki is the third villain to ring the PJ Masks’ HQ’s doorbell.
    • The first villain was Luna Girl in "Moonbreaker", and the second villain was Romeo in “Invisible Owlette”.
  • In this episode, Teacher states that the Kuiper belt is at the edge of our galaxy, whereas it is actually at the edge of our solar system.
  • The episode's storyline shows some similarity to "Gekko's Stay-at-Home Sneezes".
