Mrs. Otterton’s Bag Appears & Disappears
When Mrs. Otterton shows up in Chief Bogo’s office, to report her husband missing, we see the upset otter holding a family photo, and a purse is hanging off her left arm.
But a couple of frames later, when there is a close-up of Mrs. Otterton, suddenly the the purse is gone.
A few moments later, it is back on her arm again. This isn’t a mistake that has any bearing on the plot, but it’s definitely noticeable.
