Explorers on the Moon: Part 1 - S3-E11
Plot hole: Where did Thomson and Thompson get the pyjamas from? Tintin, Haddock, Calculus and Wolff did not bring any pyjamas aboard the shuttle with them because they were planning on sleeping in their clothes and Thomson and Thompson were only on the rocket because they were inspecting it before take-off, so they wouldn't have brought anything with them.

Other mistake: Wolff is explaining that if the motor is shut off again, the magnetic sole boots they are wearing will stop them from floating. Whilst he is explaining this, he is placing the boot straps over the Velcro. The first strap he places is only partially on, but a few frames after, a blip occurs in the animation, and the strap is suddenly entirely over the Velcro. The same happens with the second strap as well. (00:08:00)

Continuity mistake: When the crates are being lowered onto the moon, the antenna on Tintin's space suit is missing. (00:20:35)

Other mistake: Haddock is lowering crates onto the moon and looks over to see Thomson and Thompson, whilst they are heard playing around off-screen. In this shot, Haddock's antenna cannot be seen through his helmet, even though the helmet should be transparent. (00:20:40)

Audio problem: Captain Haddock's mouth doesn't move when he says "Relax? Relax?!" just after Calculus says they have to start the calculations.
Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
