Corrected entry: In the scene at April's apartment after Raphael is wounded, Donny pulls the blade out of Raph's shell and hands it to April. When she examines it, she says that the general became immortal through the stars of Kikan and his generals were turned to stone and that he lived for eternities in regret to revive his brotherhood. The stone should not have spoken of the myth since the general was frozen in stone for 3000 years.
Corrected entry: Leo was captured as the 13th monster with 4 foot soldiers present. They heard the generals talking about how Winters won't know the difference. Winters should have been informed about Leo from Karai as she stated the foot work for Winters. Karai seems to know the turtles history and the foot report to her.
Corrected entry: Towards the end of the movie, Winter's warriors state that there is only one monster left to collect. After this, the audience later follows Raphael as he battles with the supposed final monster (the little red one in the cafe)just before he fights Leonardo. After that fight, the warriors take Leo as the last monster instead of capturing the little one. However, when all of the monsters are shown in the capsules (including Leo), the small monster is there. Then at the end of the final battle, the real final monster comes running in and is many times larger than the one Raphael fought.
Corrected entry: In the older TMNT movies, when the shredder gets crushed in the garbage truck his helmet gets destroyed. In the second movie, when he comes back, he gets a new helmet and it has sharp ridged edges. In this movie they have shredder's helmet on a shelf in one scene, but it is the one from the first movie that got destroyed, not the one from the second movie which was only submerged into water along with the shredder.
Corrected entry: When the warriors realised that the lord wanted to return himself and them to mortality, why didn't they just release the 12 already captured monsters instead of relying on him not to capture the 13th himself? They couldn't have been worried about being attacked because they are immortal.Adam Bentley
