In the opening scenes Brady turns on a projector to show the movie "Wet Side Story." While watching the movie Mack and Brady stand up to dance in front of the screen. There are no images shown on Mack or Brady and no shadows on the screen from their bodies blocking the projection.

As Tanner walks down the corridor of the high school singing, a girl on his right who is watching him, takes off her glasses and holds them in front of her. As he passes her, her glasses are suddenly back on her face and her arms are at her sides.

In "Best Summer Ever," Butchy is revving his motorcycle and a girl in a black bathing suit is sitting behind the bike. Behind here are green and yellow surfboards stuck upright in the sand. Butchy revs his bike, covering the girl in sand. However, when we see black bathing girl covered in sand, she has been reoriented so that the beach is behind, leading to the entrance of the frisbee dance brigade.

When Lela first comes out of the water upon reaching Brady's and Mack's world, she is barefoot. She remains so as the ensuing song begins, but at the point when she is singing to the human mechanical man, she is wearing black heels. Not only do we not see her putting them on, but she was not even carrying them as she came out of the water.

When Brady finished looking at the college application he turned off his computer, and yet his mom asked him about the college application still on the same screen he turned off.

During the school lunch scene starting from left to right first row then bottom row, Lela's lunch tray goes from: apple, nothing, Jell-O, mixed vegetables then nuggets and mashed potatoes to: macaroni & cheese, mixed vegetables, nothing, french fries then nuggets. Tanner's lunch tray goes from nothing, nothing, nothing, mashed potatoes, then nuggets and mixed vegetables to: macaroni & cheese, mixed vegetables, nothing, mashed potatoes then nuggets.

During "Falling for ya", none of the microphones on stage are plugged in. This could be explained by this being a song in the "Wet Side Story"-movie, so there would be no need to be realistic, but one of the microphones actually HAS a cable which is then used for the joke where Seacat unplugs it to stop CheeChee from singing.

When Brady jumps off the truck during "Thats How We Do" to run up to the stage in front of the screen, another female dancer is in the way and he shoves her out of the way.

During the closing credits, a Ford Thunderbird convertible is shown. This version of the Thunderbird did not go on sale until 1964, but the movie is set in 1962.

Also in the closing credits, a VW Beetle convertible is shown. The bumper style on this example was not introduced until the 1968 model year, six years after the scene is set in 1962.

If "Wet Side Story" never existed then Mack would have not met Brady and Mack's Aunt would have sent her to a different school.

The song "Best Summer Ever" mention songs from the previous movie sang exclusively by Mack and Brady like "Can't Stop Singing" and "Surf's Up". That means Mack and Brady changed the movie, which had to affect the external world the way Lela's modification did, but it didn't.
