Vendetta

In the Nickelodeon series they have been teasing us with hints towards what the Kraang are up to on Earth.  We learned that they are working at fixing the Mutagen so it works how they want it to on Earth.  We find they are trying to change Earth's environment to match theirs and we are shown that they want to catch April O'Neil.  Each of these bits of information is given to us little at a time and keeps us hanging on waiting for more.  In the newest episode of Nickelodeon TMNT the Foot learn that the Kraang are after April O'Neil and join in on trying to catch the Turtles friend.
