The father almost forfeits the baseball game because of a shortage of players, but after Rocky, Colt, TumTum, and the Japanese girl show up, a mass of kids are shown on the bench.
In the first film, Colt is shown as being able to throw stars with strong accuracy. He is even able to throw CD's at Marcus and Hammer. Yet, in this film, Miyo has to train him to throw stars because he can not do it.
in the beginning of the movie the farting baseball players number was #11 but at the end of the movie his number change to #10.
Colt's hair before and after he gets hit on the head by the baseball.
After Colt hits the home run to end the final game, he takes his helmet off before he reaches second base. In baseball, this would result in his run not counting. This would cause the game to be tied instead of over.
The boys clearly span in age range from about 5 to 6 years, yet all play on the same baseball team. This would not happen as the range for most youth sports is about 2 years.
When Tum Tum gets his last hit in the final game, he's stepping on home plate. In baseball, this would result in an automatic out.
When the Three Ninjas arrive to Japan, the song that is playing is by Seo Taeji. They, and the lyrics they sing, are both Korean.
When the boys are ordering the tickets to Tokyo using their grandpas recording from the answering machine, Colt plays the part where Mori Shintaro screams. The problem is after the lady asks if the price is OK Colt makes the tape say "yeah everything" , but the problem is their grandpa said "yeah they took everything" so there would be no way Colt could get past those two words that fast without listening to make sure he hit the right words.
When the fat kid starts to fart when he runs the bases, some of the people in the crowd start to fall over before the fat kid passes.
When Slam and Vinnie are attempting to break open the front door of Grandpa's cabin, Rocky sits on top of a nearby tree behind them and pulls a semi invisible wire that is tied to the doorknob, causing them to fall into the house. However, the door is an inward opening door. Thus, this gag does not make sense.
As Miyo, Tum Tum and Colt are going to follow Rocky down the slide he falls down in the cave of gold, the little wheel cart/mechanism used to slide the three down is clearly viable when they hop on it and slide down. You can see a white board when they sit down, yet when they slide away you can tell the white board is gone.
When Slam is pied in the face and knocked over by Tum Tum in the cabin, you can clearly see him reaching to the hiding spot for the dagger and purposefully exposing it as he knocks over shelves.
When the kids are sliding down the secret passageway in the cave of gold and Rocky is the last one sliding down, Rocky's voice is higher than it is in the rest of the movie.
When Tum Tum is yelling Ninjanuity to cheer on Colt, his mouth and his words don't match up.
At numerous points throughout the film, it is made clear that the boys know little Japanese, even setting it up by having Miyo teach Rocky. However, Colt is somehow able to impersonate a Japanese contestant in the tournament. He is able to explain that he is not hurt anymore, and able to return to the tournament.
In the first film, Rocky bests the bullies at the end. In Kick Back, one of the bullies has seemed to have forgotten that the three of them are skilled enough to defeat him.
In the beginning of the movie the farting baseball players number was #11 but at the end of the movie his number change to #10.
