Simple bad luck, or good luck. I suppose it all depends on how you feel about turtles.
The Teenage Mutant Ninja Turtles (often shortened to TMNT or Ninja Turtles) are a fictional team of four teenage anthropomorphic turtles, who were trained by their anthropomorphic rat sensei in the art of ninjutsu and named after four Renaissance artists. From their home in the storm sewers of New York City, they battle petty criminals, evil overlords and alien invaders, all while remaining isolated from society-at-large.
The characters appeared in comic books before their expansion to cartoons, video games, films, toys and other general merchandise. During the peak of its popularity in the late 1980s through early 1990s, the franchise gained considerable worldwide success and fame. Chrysemys
