The T-Rawket is a vehicle Donatello invented so the Turtles could go after the Kraang Scout Ship in the episode The Mutation Situation. It's built from a Coney Island amusement park rollercoaster-like ride car and a fully functional rocket engine. It runs along the subway rails until reaching the surface where it rockets into the sky. Launching the Turtles away in their Turtle Flyers.
