Catboy is on the moon, admiring its beauty and mysterious nature. He holds up a moon crystal, which Luna Girl quickly snatches from him. Owlette arrives and has Luna Girl focus her attention about a bigger moon fortress. She grabs the crystal from the villainess, but she is caught by the Luna Magnet’s rays and drops the crystal as she is shaken. Luna Girl returns to the Lunar Fortress with the crystal in her possession, not knowing that Gekko is inside as well. He takes it from her, but it falls out of his hands as he trips midway.
The PJ Masks chase Luna Girl on their PJ Rovers as she makes her getaway with the moon crystal. Luna Girl places the crystal in her Luna Magnet, and with her Luna Wand, she creates a crystal barrier to prevent the PJ Masks from advancing any further. Her victory is short-lived, though, as the crystal falls out from the magnet.
Catboy obtains the moon crystal and claims that Luna Girl beat the PJ Masks fair and square. He offers the crystal to her, but while she isn’t looking, he switches it with a normal moon rock and gives that to her instead. She finally notices as she flies away, and she chases the PJ Masks, vowing to get them for this.
Luna Girl’s Luna Wand makes its seventh appearance.
