The Crab with the Golden Claws: Part 1 - S1-E1
Continuity mistake: Tintin and Snowy are walking to Thomson and Thompson's office and Tintin is shown saying to Snowy "Come on, Snowy. The Thompsons are waiting for us." In this shot, there is a wooden fence located next to them that is a very pale beige color. In the next shot, from a close-up of Snowy, they are now standing next to a fence that is a very bright brown color. (00:02:40)
