Corrected entry: Mario says about his girlfriend "I promised to take her to Wrestlemania." The problem is that Wrestlemania took place in Las Vegas that year. The event took place in NYC's MSG the following year.
Corrected entry: Throughout the entire movie where Koopa shoves someone in the De-evolutionary chamber, the time that they stay in the chamber goes from fifteen seconds (Toad) to ten seconds (Koopa) to five seconds (Iggy) To one second (Spike). Why does the process shorten each time? (00:36:25 - 00:47:55)
Corrected entry: When Mario & Luigi are driving between the two police cars & the cars are blasting fire at Mario & Luigi, Mario then hits the brakes, making the two cops blast each other. Later, when they're driving through an unfinished tunnel, Mario yells, "There are no brakes."
Corrected entry: When Koopa de-evolves the Human into a monkey, just after the worlds merge, it takes a second or two. Yet when Mario and Luigi both try to de-evolve Koopa it takes longer and he does not fully de-evolve with BOTH devo guns on him. (01:30:55 - 01:33:25)
