Continuity mistake: When Mummy is asking Peppa about her new red shoes Mr Dinosaur is not in George's bed, but when George says goodnight, Mr Dinosaur is right next to him.
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.
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 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)
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 Peppa and her family walk out their house to find Mr. Dinosaur, George is smiling. When Peppa and family arrive in front of the tree, George is frowning. (00:03:46)
Suggested correction: In the shot after the family walks out of the house, it takes about 7 seconds for George and the two parents to come into the shot. There is absolutely no doubt that they had enough time to change their facial expressions.
Continuity mistake: After Peppa claims Daddy Pig's pieces in their game, they sit in front of her, but when George runs into the room sobbing, they vanish.
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: They don't have teeth until they go to the dentist.
Suggested correction: We can see Peppa and George's teeth when Peppa asks George if his teeth are clean like hers. This is before they are at the dentist.
