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 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)
