Summary
Highlights
Romeo uses a 'multiplying machine' to create multiple robots. Catboy tries to steal the machine, but Romeo creates a duplicate. Owlette and Gekko try to intervene, but the multiplying machine accidentally hits Catboy, creating multiple, individualistic Catboys. The PJ Masks must learn to work as a team despite the new additions, facing Romeo's growing robot army and the multiplied Catboys' conflicting plans.
Gekko accidentally uses Romeo's 'small-sizer' in reverse, making himself giant. He then attempts to use the super-sizer on a bin to trap Luna Girl's moths, but instead makes the bin, and later the moths, giant. This causes more chaos, as Luna Girl uses a giant moth as her new luna-board. Gekko, feeling responsible for the mess, must find a way to shrink everything back to normal and learn to clean up his own messes.
Luna Girl steals all the Christmas decorations and presents. Gekko is hesitant to try new things like riding Luna Girl's Luna Board, but Catboy and Owlette encourage him. After multiple attempts and realizing he must try, Gekko successfully rides the Luna Board, retrieves the stolen items, and, surprisingly, invites Luna Girl to spend Christmas Eve with them, teaching her about the spirit of giving and togetherness.
The new fairground flyer train disappears, and Owlette, excited by speed, rushes ahead without waiting for her team. They discover Romeo is using a 'tracker-whacker' to create and remove train tracks, stealing the train and his lab to make the train even faster. Owlette learns that slowing down and working as a team is crucial to catch Romeo and bring the train back safely.
Romeo freezes the city to create an icy roller coaster for his 'lab-toboggans', intending to take over the world. Catboy and Owlette struggle on the ice, but Gekko, using his 'super lizard grip', is uniquely suited for the slippery conditions. After his initial ideas are dismissed, Gekko finally asserts his plan and uses his powers to defeat Romeo, demonstrating the importance of trusting each other's ideas and special abilities.
