Continuity mistake: As Porky's Riverboat nears the draw bridge, you see Pee Wee activate the bridge so that it begins to lower. Look at the angle of the bridge as Pee Wee is running by it, making his getaway. The bridge is almost down. The scene cuts to the River Boat's view and you can see that the draw bridge is all the way up and just starting to come down.
Continuity mistake: When Meat, Bryan, and Billy are in the small boat being chased by Porky's riverboat, watch Meat's position while they are rowing and trying to start the motor. As the camera changes angles, Meat goes from lying down to sitting up to lying down again.
Continuity mistake: At the end of the movie when Meat, Bryan, and Billy are jumping off the River boat into the water, watch the water as each one jumps in. All three jump in almost on top of each other, but the water seems to remain calm and undisturbed after each one jumps.
Continuity mistake: When Balbricker and Snooky reunite on the beach, she drops her hat and his falls off when they run to each other. In the next shot when they are lying down on the beach they both have their hats back on.
