Factual error: When everyone went up in the hot air balloon the sun and the moon are both visible. The illuminated side of the moon is facing in the wrong/other direction from the sun, which doesn't work.
Continuity mistake: When Mr. Rabbit says "Rabbits love carrots," there are 3 carrots on Peppa's plate. When George eats a carrot in the next shot, the carrots disappear.
George Catches a Cold - S2-E20
Continuity mistake: When Peppa and her family come inside the house because of the heavy rain, the door behind Daddy Pig is open. But a few seconds later, the door is closed. (00:01:01)
Suggested correction: This doesn't occur between shots, and the 2 screenshots are not consecutive changes. The "few seconds later" is an 8-second close-up of George as he begins to sneeze, and the front door is not visible. Within those 8 seconds off-screen, there's time for the door to be closed and to set aside the two umbrellas.
Continuity mistake: When Peppa talks about her parents getting a Playgroup Star, the picture that Peppa made has a white background. When Peppa asks Daddy Pig if he did get a Playgroup Star or not, the picture that Peppa made now has a blue background. (00:00:49 - 00:01:11)
Continuity mistake: When Peppa is singing, George is next to her. But in the next shot, he is with Mummy Pig and Miss Rabbit. Also, one of three characters disappear in the previous shot. And after Peppa is singing, everyone is gone, but they reappear when they all laugh. (00:02:09 - 00:03:03)
Continuity mistake: When all the children greet Emily Elephant at the beginning, Madame Gazelle is next to her. But in the next shot, Madame Gazelle is gone. (00:00:37)
Continuity mistake: When George doesn't like the tomatoes, lettuce, or cucumbers in the kitchen, there are two tomatoes on his plate. When he eats his pizza, there is only one tomato left and the fork has disappeared. (00:02:56)
