 There is an additional scene that was supposed to take place at the end of  the movie in which April and Danny go into the offices at Mirage comics to  pitch a story about teenage mutant ninja turtles. The publisher turns them  away claiming the idea to be too "farfetched" the turtles pop their heads out  of each window corner behind the publisher For some reason this bit made it  into the book adaptation as well as the sticker book (with pictures), but was  left out of the movie.
