On the moon, the PJ Masks are just finishing packing up some crates in HQ. As they grab their cuddlies, they prepare to take off, but PJ Robot stops them. He indicates on the screen that he forgot his elephant cuddly, Frank, on the moon. The team assures him that they will get it back, and they take off in the PJ Rovers.
A few moments later, the PJ Masks arrive at the spot where PJ Robot's cuddly is located. Catboy picks it up, but an overexcited PJ Robot quickly flies up to and crashes into him, causing the cuddly to be thrown up in the air. Catboy and Owlette both fail in retrieving it, but Gekko throws a moon boulder against a couple of floating moon boulders around the cuddly. The huge rock hits the toy towards PJ Robot, and he happily grabs and hugs it. Catboy announces that they can finally go home, until Owlette reveals that she left her cuddly somewhere on the moon during the retrieval of PJ Robot's cuddly.
Moral/Lesson
Don't be forgetful.
Trivia
Catboy tells Gekko about the Apollo 11 mission: 50 years ago, 3 astronauts lifted off and became the first men who walked on the moon, specifically in the year 1969. He does this by saying "Hate to break it to you, Gekko, but fifty years ago, they did."
In regards to the quote, this is the third use of the word "hate" in PJ Masks, which could be suggestive/inappropriate for some viewers.
It is revealed that PJ Robot has a cuddly.
The cuddly is an elephant named Frank.
This is the first time Owlette was seen and heard kissing something.
This is the third short where all the villains are absent.
This is the first short to end in a cliffhanger since Owlette left Lady Wigglesworth somewhere on the moon, so it is unknown if the PJ Masks did find the cuddly. Either Luna Girl has it or Owlette just placed it on a moon rock.
This is also the fourth time including full episodes that PJ Masks ended in a cliffhanger.
