There are plenty of differences.
The board is different.
The game itself has been around for about 35+ years, so while the trap pieces don't seem to have changed much, the board graphics probably will have been refreshed many times.

If you look at the green diving man, the red bath and blue pipe work, there are noticeable differences.
The animation at Maxon has the small mouse shaped playing pieces with thin tails that I remember, the ones in tjohn's are bigger and a different style.
