The Crab with the Golden Claws: Part 1 - S1-E1
Continuity mistake: When Tintin and Haddock discover the sea plane headed for them, Tintin states it is coming in very fast, to which Haddock replies "Not fast enough for me." As he says this, his arms are shown waving around and that his right arm is raised far above his left arm. In the sudden shot following, Haddock's arms are now completely still and are partially lowered. (00:19:45)
