The short starts off with the PJ Rocketship parked near the Lunar Fortress as the PJ Masks run to the structure. Gekko is afraid of this because Luna Girl does not like guests and might trap them, but the others assure him that Luna Girl can only get to the moon with their help.
They proceed inside with delight as they look at all the pictures Luna Girl hung on the wall. Catboy sees a crystal and wonders if it is real. He pulls back as he touches it with a yelp, but is otherwise unharmed. Gekko loudly climbs up the wall as Catboy runs to Luna Girl's throne, warning him to be quiet. Sitting on the chair, Catboy talks about the room when Luna Girl jumps behind them, frightening the PJs. Gekko asks what she was doing there, to which she replies by saying she was enjoying the harvest moon, and asked what they were doing there. This leaves the PJ Masks nervous to tell the truth. Owlette replies they should’ve knocked first, but wanted to see the fortress. Luna Girl, slightly surprised, says she’d give them a tour. The PJs begin to leave as Catboy says that it was time to go, but Luna Girl swerves in front of them to block their way out, saying they cannot leave without seeing her amazing fortress, and giggles and twirls around as she begins the tour.
She twirls around, demonstrating her space to swoosh around and look good. She then sits in her throne and says that’s where she relaxes after a day of mischief. Walking towards the statue, Owlette sarcastically says if one statue is enough. Luna Girl agrees, and jumps up to zap up some more statues. The PJs smirk as they wave bye to the trapped Luna Girl. Catboy insists they should do play dates on Earth next time as they exit the fortress, ending the short.
This short, along with the previous short, may had taken place after the events where Luna Girl had reclaimed the Moon Crystal from the remains of the Mega Magnet to restore her Luna Wand. This may include that the short and "Moon Rocked" were produced when Season 4 was in production, even though Kyle Harrison Breitkopf was still voicing Gekko at the time.
