Continuity mistake: The gang investigates the trail of limestone to a manhole in the middle of the street, with nothing around it. But when Daphne is putting on her "Wallowing galoshes" boots, somehow a small brick wall just materializes in the middle of the street for her to sit on - and then vanishes a couple shots later. Not just the fact that it appears and vanishes between shots, but that there is a random brick wall in the middle of the road. (00:05:10)
Continuity mistake: When Mr Bean realises that the Burglars are behind him, the small burglar's left gold earring disappears. After they tie up Mr Bean, it reappears.

Max's Bath - S1-E4
Continuity mistake: When Max finishes his shower, his toy duck and bath robe are on the heater, but when Ruby looks at her dirty dress, they have vanished. A door also appears behind Ruby, which was never there previously in the episode.
