Continuity mistake: When the elephants in the circus are making a pyramid on top of a ball, as it changes from shot to shot the colour of the blankets on their backs changes, and one of the elephants changes from grey to blue.
Continuity mistake: At the end of "When I See an Elephant Fly," the crows laugh and tumble to the ground. In the two shots of them laughing on the ground, you can see a crow dressed in red and pink with a cigar in his mouth on the left side of the screen. This crow plus the four other crows in the shot PLUS the leader of the crows equals six crows. Throughout the rest of the sequence, there are only five crows, and the extra crow is never seen again.
Continuity mistake: The same shot of the two elephants holding each other's trunks when the pyramid of elephants starts to collapse is shown twice.
Continuity mistake: The number of elephants change constantly throughout the movie. Especially when the ringmaster introduces the elephant pyramid act, and there are 8 elephants in the ring, yet the finished pyramid only has 7.
Continuity mistake: During the pyramid of pachyderms scene one elephant grabs an elephant by the tail with her trunk. The elephant that is being lifted has a blue blanket and blue hat as she is being lifted and swung. In the very next shot they change to purple.
Continuity mistake: When the stork gives Dumbo to Dumbo's mother, he tells her to sign a paper. Dumbo's mum writes an "X" mark in the sign space. On the paper is a "Received one elephant" picture, a sign that says "Signed" at the bottom and loads of dots next to it. In the next shot, the paper is totally blank, excluding the "X" mark.
