Amaya tells Greg to take his project "one step at a time", but then Connor finds out that the school field trip to the observatory was cancelled because a giant telescope was stolen. By night, the PJ Masks find out that Romeo stole the telescope for his Space Laser because he wants to carve a picture of himself ON THE MOON! However, one of Luna Girl's moths found out about Romeo's plan. Romeo then drives to a different part of the town to fire his Space Laser, but then Gekko finds a furious Luna Girl telling him that she won't let Romeo shoot the moon. Gekko now has 5 problems to deal with: Romeo, Robot, the Space Laser, Luna Girl, AND Luna Girl's moths! But then Gekko has a plan: He calls for Luna Girl to stop Romeo from shooting the Moon.
