Teenage Mutant Ninja Turtles & Splinter

The Teenage Mutant Ninja Turtles (often shortened to TMNT or Ninja Turtles) are a fictional team of four teenage anthropomorphic turtles, named after four Renaissance artists, who were trained by their anthropomorphic rat sensei in the art of ninjutsu. From their home in the storm sewers of New York City, they battle petty criminals, evil overlords, mutated creatures, and alien invaders while attempting to remain hidden from society.
