Trivia: When Splinter reveals that he knows April and she speaks his name, the camera pans over Mikey as he asks if she is a Jedi and he can be seen holding a can of Orange Crush. As promotion for the movie, Mikey was featured on the boxes of Orange Crush soda once the movie came out. Similarly with Donnie on Grape Crush and Raph on Strawberry Crush.

Question: How does Splinter know who shredder is? It's established that his first memories are from the lab so that's how he knows Eric Sacks is a bad guy and April saved them, but how does Splinter know Sacks is working for the foot and is connected to shredder? He even knows shredder trained Sacks as a boy, but this was in Japan, 20 to 30 years before Splinter was around.
