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.
Don't be forgetful.
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.
In regards to the quote that Catboy uses ("Hate to break it to you, Gekko, but fifty years ago, they did."), this is the fifth use of the word "hate" in PJ Masks, which could be suggestive/inappropriate for some viewers.
Mr. Meow, Lionel Jr. and Lady Wigglesworth all make their returning appearance since "Catboy's Cuddly."
