Did you get it right?
The two bait-shop dock panels contain five visible changes.

The Answer
The correct answer is: five changes involving the bait sign, bobber, tackle box latch, duck direction, and small dock/rope details.
Here is why
- The bait shop sign changes from 25 in panel A to 35 in panel B.
- The hanging bobber changes from red-and-white in panel A to white in panel B.
- The tackle box latch is different between the two panels.
- The duck on the water faces a different direction in the lower panel.
- A small dock/rope detail near the rowboat and post changes between panels.
Why people miss it
The people and boat make the panels feel almost identical, while the changes sit in small sign, gear, and water details.
