Unwanted Guest: Part One - S5-E1
Revealing mistake: After Kaiba has finished explaining the KaibaCorp Grand Championship, there is a wide shot of the office where Kaiba says to Mokuba, "Good idea." In the wide shot, Kaiba's body appears to be unnaturally small, and his arms and legs appear even tinier. (00:07:36)
Unwanted Guest: Part One - S5-E1
Revealing mistake: When Mokuba is showing everyone the new duelling field, in the shot of Joey saying "Not too shabby," the Millennium Puzzle that Yugi is wearing is animated completely wrong. Instead of the hole in the centre and the designs that are shown on the front side of the puzzle, there is only one awkwardly drawn shape. (00:12:06)
