Tintin in Tibet: Part 2 - S2-E7
Continuity mistake: When Haddock first wakes at the monastery, he finds a scarf that is a pale yellow color. Next shot, that same scarf is suddenly a lot darker (still yellow). (00:32:55)

Continuity mistake: Snowy lets go of a note to bite a bone and it falls an inch away from him. But as soon as he takes off running, the note isn't visible next to the bone. (00:31:10)
Tintin in Tibet: Part 2 - S2-E7
Continuity mistake: An emperor at the monastery begins floating in the air. From one angle, he is a foot in the air. But from another angle, he is suddenly a meter in the air. (00:29:55)
Tintin in Tibet: Part 2 - S2-E7

Tintin in Tibet: Part 2 - S2-E7
Other mistake: Haddock becomes exhausted and sits down. Tintin points out he'll freeze. Watch the two horizontal strips along the middle of his jacket. They are yellow for a few frames, then they go to blue for a few frames. Then if you look super carefully, you'll see that the two straps vanish from shot for a quick frame. Then they reappear.

Tintin in Tibet: Part 2 - S2-E7
Other mistake: As Tintin, Haddock and Tharkey set up camp, Tintin gets blown back by the tent. Tintin starts running as he is pulled by the tent and trips once he lets go. You'll notice that there is a huge skid mark from his landing on the ground before he does so. (00:28:30)

Other mistake: When Tintin is running as he is being dragged by the tent, he leaves no footprints in the snow. (00:28:25)
Tintin in Tibet: Part 2 - S2-E7
Continuity mistake: After Tintin thanks Tharkey, they proceed with their journey. From a wide angle, footprints are made in the snow as they take each step. But in a close-up of the adventurers, their tracks are now in the shape of a skid mark. (00:28:05)

Continuity mistake: Tintin's hat is yellow when Tharkey comes to the rescue, but grey when they are thanking him. (00:27:30)
Tintin in Tibet: Part 2 - S2-E7
Continuity mistake: When Haddock goes to cut the rope, he ends up dropping his Swiss army knife. As it drops, the knife has a small ridge in it for opening with a thumbnail. In the following shot, when it is shown falling, the knife is still facing the same direction, but the ridge is no longer visible. Then in the next shot, the ridge is back again. (00:27:15)
Tintin in Tibet: Part 2 - S2-E7
Continuity mistake: After Tintin and Haddock find the scarf, they continue climbing the rocks. Tintin climbs onto a rock which has a clear smooth shaping on the top. Yet from another angle of the rock, the top of the rock is now shaped differently. (00:26:10)
Tintin in Tibet: Part 2 - S2-E7
Continuity mistake: When Tharkey points out that they must leave, Haddock walks over a hill where footprints are visible behind him and Tintin. But when Tintin points out there is a scarf on the mountain, the footsteps behind him have vanished. (00:25:00)
Tintin in Tibet: Part 2 - S2-E7
Revealing mistake: After the "previously" clip, Tintin, Haddock, Snowy and Tharkey continue their walk. In the second shot, the four walk over a hill. The first footstep on the edge of the hill is incorrectly drawn and looks unrealistic. (00:24:45)
