In the carnival scene, when Popeye, Olive, Bluto, and a pig are at the "Test Your Strength" game, Bluto grabs the pig (who is holding the mallet) and slams the pig and mallet on the shooter. Two shots later, the pig is no longer holding the mallet.

When Betty Boop is dancing at the carnival, she goes from being in front of one poster to the next without even moving to the side.

At the carnival, the "Test Your Strength" mallet suddenly appears out of nowhere on the ground in one shot. The mallet appears on the ground as that is likely where it landed when the pig let go of it.
