In the beginning of the movie Giggywig has one badge on his collar, from the middle of the movie he has two badges.
In the latter half of the film, whenever Wrenchmuller takes a picture, you can see that his camera is missing its lens.
In the opening scene, when Sherrif Hoxley is getting a bottle of soda pop out of the machine and talking to Russell on his radio, reflected in the window over the machine are two rather-tall palm trees, trees which are not native to Big Bean, Illinois.
