Destination Moon: Part 2 - S3-E10
Continuity mistake: Right before the launch, Haddock is wearing blue coveralls, but after the towers are cleared, they are green for one shot, only to be blue again for the rest of the episode.

Continuity mistake: When Tintin follows the mob member from the diner to the building, the scene cuts to an exterior shot. A hot dog stand is shown outside the building, with a vendor standing beside it, but in the next shot, the vendor is suddenly standing behind it. (00:16:40)

Continuity mistake: As Tintin and Snowy are walking out of the train station, there are two taxis parked outside. When Tintin is offered a ride, there is only one taxi, and the other taxi has been replaced by a purple car. (00:02:25)

Explorers on the Moon: Part 2 - S3-E12
Continuity mistake: When driving to the landing pad, the number plate is shown to have fairly thin style numbering, but later in the scene, when the car is shown through the view of the binoculars, the numbering on the plate is much thicker. (00:41:05)

Explorers on the Moon: Part 2 - S3-E12
Continuity mistake: In the tank, Haddock removes his helmet and he starts banging his head due to the bumpy moon surface. The shot cuts to an angle of the tank driving and the helmet has suddenly reappeared on his head. (00:26:50)

Explorers on the Moon: Part 1 - S3-E11
Continuity mistake: When the crates are being lowered onto the moon, the antenna on Tintin's space suit is missing. (00:20:35)

Explorers on the Moon: Part 1 - S3-E11
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)

Destination Moon: Part 2 - S3-E10
Continuity mistake: When Calculus is showing Tintin and Haddock the airlocks in the rocket, there are three levers shown, two of which are level with each other. Once Calculus has been told to return to the centre, the two levers that were level with each are now in two different positions. (00:32:15)

Destination Moon: Part 2 - S3-E10
Continuity mistake: Calculus is showing Tintin and Haddock the living quarters of the rocket. Haddock has a red button on the back of his space suit, which becomes a grey button once he is climbing down to the next deck below. (00:31:50)

Destination Moon: Part 2 - S3-E10
Continuity mistake: When Calculus is driving himself, Tintin and Haddock out of the base, Calculus drives down a hill and back onto the main road. Haddock is still sitting in his seat, but in the next shot, he is suddenly standing up. (00:30:15)

Destination Moon: Part 2 - S3-E10
Continuity mistake: The plane that lands in Syldavia has a yellow stripe when it is first landing, but has a blue stripe when the passengers are exiting the plane. (00:25:05)

Destination Moon: Part 1 - S3-E9
Continuity mistake: When Tintin sees the detonator for the rocket, the two levers controlling the rocket are seen behind him. The levers are both level with each other, but once Tintin has rewired the detonator, the levers are in two different positions. (00:20:00)

Destination Moon: Part 1 - S3-E9
Continuity mistake: To launch the model rocket into outer space, Tintin pushes a lever with a green handle. Once the control tower is told to engage the nuclear motor, the first lever that Tintin had pushed is now a blue lever and the second lever that Tintin is now holding onto is a grey lever. Two shots after that, both the levers are now green. (00:16:00 - 00:16:35)

Destination Moon: Part 1 - S3-E9
Continuity mistake: When the car taking Tintin, Haddock and Snowy to meet with Calculus leaves the airport, the number plate is 1941, but when they are welcomed after entering the base, the number plate is now 1491. (00:02:10 - 00:03:45)

The Castafiore Emerald: Part 2 - S3-E8
Continuity mistake: When Castafiore is complaining about the stairs not being fixed, the first shot of her shows nothing on the torso section of the dress she is wearing, but when the shot is on her next, a small design has suddenly appeared on the chest area of her dress. (00:24:55)

The Castafiore Emerald: Part 1 - S3-E7
Revealing mistake: When Castafiore is showing everyone the Castafiore emerald, after she says "He named it in my honour", the shot cuts to a close-up of her hand, saying "The Castafiore Emerald." At the start of the shot, she has two rings on two fingers, then she turns her hand and the two rings vanish from her fingers entirely. (00:09:00)

The Castafiore Emerald: Part 1 - S3-E7
Continuity mistake: After Haddock tells the gypsies that they can camp near Marlinspike Hall, Tintin and Haddock return to the manor. As they walk up the stairs, Haddock has his cane in his left hand, but when they walk through the door, Haddock suddenly has his cane in his right hand. (00:03:35)

Prisoners of the Sun: Part 2 - S3-E6
Continuity mistake: When Tintin climbs up the cliff to rescue Snowy from the condor's nest, he is carrying a rope over his right shoulder, but from a much further away angle, the rope is suddenly placed over his left shoulder. (00:26:10)

Prisoners of the Sun: Part 1 - S3-E5
Revealing mistake: When Tintin is swimming back to the boat after escaping the ship, Haddock is quickly rowing back and forth to reach him in time. As Haddock rows, the bars used to place the oars through can be seen moving back and forth, along with the movements of the oars, even though the bars are supposed to remain still during the oar movements. There are also frames from this shot where the bars vanish from the frame entirely as Haddock rows. (00:07:25)

The Seven Crystal Balls: Part 2 - S3-E4
Factual error: The shed that the intruder fires at Tintin and Haddock from has a lock shown on the interior side of the door, but no lock shown from the exterior side of the door. (00:30:15)
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.
