Plot hole: April and Kenshin switch place in time as they were - by some extraordinary coincidence - holding the scepter "at the same time" (if the concept makes any sense) in the exact same pose, with a switch that takes several second of intense lightning storms and 'tornado weather' as one of the Turtles put it. Here there is the assumption that 4 priests would be around the scepter exactly at the same time, and when the Turtles do switch with Norinaga's elite soldiers instead they certainly were in completely different poses, far away enough to ride horses, who did not get spooked one bit by the lightnings and sudden winds but rode as if nothing happened.

Plot hole: In the beginning after Flint buries the treasure, he kills all the men that are with him. The pistols he has are one-shot pistols, so there's no way he could kill 14 men using only two one-shot pistols.

Plot hole: In the river scene, Betameche states that his pocket knife doesn't have rope, as it's only available on the smaller model. Yet, around 10 minutes later, Princess Selinia is pulling a retracting rope from the pocket knife, allowing them to abseil down. (00:45:00 - 01:00:00)

Plot hole: It's never really addressed or explained how Shredder survived his death in the previous movie from being crushed in a garbage truck.
Suggested correction: It didn't really need to be addressed, and thus is not a mistake. His hand emerging from the junkyard is enough to show that he survived his apparent demise at the end of the last film.

Plot hole: When Injun Joe is about to kill Huck, Tom takes notice of the chest full of gold coins and then empties the chest out (offscreen) because it was too heavy for him to lift, and then tricks Injun Joe into trying to retrieve the empty chest, resulting in Injun Joe falling to his death. The amount of time that passes between Tom glancing at the chest and then tricking Injun Joe before he can kill Huck is roughly 5 seconds. There's no way Tom could have emptied out of the chest in that little amount of time if the chest was too heavy for him to lift in the first place, especially without making a sound.

Plot hole: In the first film, the shape of the ring was a little different and it was set in a ring. Also, it was given to Xania. In the second film, she was never even acknowledged as donating it to the museum.

Plot hole: Emily begins to pull Henry out of the shed, but however there is no track leading to the other end. Also, the turntable is not big enough for both engines to fit on.

Plot hole: Even if Chicken Little was tagged out when he hit home plate, the game was already tied so his team would still have a chance to win the pennant.

Plot hole: Lots of police officers saw Santa flying at the end. This should've caused the world to accept Santa was real.
Suggested correction: From ONE location? Also, people wouldn't believe in Santa that easily.
Suggested correction: It should also be noted there were no cameras to capture the event, and not many eyewitnesses. Only a few neighbours and some officers. Even if these folks now believe in Santa, who's going to believe them? Folks they tell are going to think these folks are making it up, that their brain or someone else played a trick on them, or that they are mentally disturbed.

Plot hole: If Chester's plan was to steal the machine the entire time why didn't he just have his people steal the machine while it was still floating in the air during the first film? There was plenty of time to capture it before the food started mutating so what was he waiting for if he needed it so bad?
Suggested correction: Because he wasn't there in the first film? He first made an appearance in this film, doesn't know how to work the machine without Flint, and how the hell would he even get it in the sky? He also didn't even know about it, or what happened to Chew and Swallow, again, until he made an appearance in this film. Not a mistake.

Plot hole: When Dubois attempts to kidnap Alex using the tranquilizer, she is brought to a halt by several different zoo staff thanking her for returning him. The entire first movie's plot is based on them being stranded on Madagascar after being on a ship that was intended to take them away. The actions of the animals at the train station were on the news, and a large gathering of sorts was held to show that the animals were leaving the zoo. Therefore, no one should have reacted this way to his return.

Plot hole: If Minh knew about the Power Rangers, their identities and their history, it makes no sense that she would expect to morph without being specifically chosen to become the Yellow Ranger.
Suggested correction: The rebel teenager archetype. If I had a dime for every time a kid didn't listen I would be a billionaire. It's not a mistake.
It doesn't make sense at all that Minh would expect to morph just because she had a power coin in her possession; she had to have been told about how it works.
Pretend that morpher is a gun and she's a teenager in the real world. To say no teen would pick it up, disobey an adult, just try it themselves is a joke. She's a kid. Kids do stupid stuff and don't listen.
I'm sorry, but I disagree. We are talking about the daughter of a Power Ranger, not a typical teenager. Trini, being the type of person she was, would have explained how it works; it is highly unlikely that Minh would make such a careless choice.
She didn't discover her mom was a Power Ranger until after death. There was a whole scene where she walked in, and Billy and Zach accidentally revealed it to her. Also, itization. All she's done was make careless, impulsive choices.

Plot hole: During the bedroom scene, when Dennis shoves a flashlight into Mr. Wilson's mouth and nose, Wilson opens his eyes. It would be impossible for Dennis not to notice his open eyes, and realise he's faking being asleep, especially when he puts the light into Wilson's nose.

Plot hole: When Quasimodo is revealed to the crowd during the Festival of Fools, someone identifies him as "the bell-ringer from Notre Dame." This is the first time Quasimodo has ever left the cathedral, so he shouldn't know that.

Plot hole: There is no reason that Eden Hall couldn't have accepted the Ducks and also kept some of the JV players as well other than they didn't want to hire more actors for the team. Keep in mind, by the time the Ducks actually attend E.H. they only have 12 players (with two goalies). Once Banks gets transferred to Varsity they only have 9 skaters. Surely they could have allowed the cut JV players to rejoin the team since they barely had enough skaters for 2 full lines.
