Continuity mistake: Immediately prior to pushing the lizard down the chimney you can see teeth appear in the dodo's mouth for a few frames. (00:23:49)
Suggested correction: And how would that happen accidentally? The animators would have to deliberately draw the teeth. It was obviously done for effect. It is even done later in the scene. Most likely, the mouth wouldn't read correctly for certain words if teeth weren't visible.
Continuity mistake: When Alice becomes a giant a wide shot of the garden shows the main entrance's broken door leaning on her left foot. First of all, the rabbit managed to open it before she burst it with her right foot. Second of all, when she shrinks, the door appears magically back in its place. And no, it's not a different door because at 00:21:05 we see the house and there is no door where her left foot later comes out through.
Suggested correction: All throughout the growth sequence, the rabbit was shown by Alice's right foot. It could be possible this specific door on the left is a different door altogether.
