The Crab with the Golden Claws: Part 1 - S1-E1
Continuity mistake: Just as the scene at the docks starts, Tintin stops by a rope and looks up to notice the Karaboudjan. In this shot, the ropes are located right beside him, only a foot away. Allan and one of the crew members then begin conversation and the angle changes, showing Tintin far in the background, but the ropes are nowhere to be seen. (00:08:00)
