Factual error: After Berry and one of the Country Bears get in the bus to find the others, they show a scene with the bus going along a road and Berry leans out the window. Here you can see the side of the bus is spick 'n' span clean. Then, later, the bus is as dirty as it was when it left the shack, very noticeable at the start of the carwash scene.
Continuity mistake: Augustine's hair has a life of its own. It becomes messed up a few shots before she fights with Gaby, then is back to its proper position during the piano shot of her song, then it's back to messy - but in a different way than before - for the standing up part of the song.Sereenie
