Heroes in a half shell, Turtle Power.
In the UK, this was renamed to HERO turtles, whereas in every other country on earth it was NINJA turtles.
It featured Leonardo, Donatello, Raphaelle and Michaelangelo as four turtles who fell into the sewer, got dunked in some toxic waste, raised by a rat (Splinter) and all grew into intelligent beings.
They had to fight various battles with Shredder, and his two sidekicks Beebop and Rocksteady, while the news reporter, April O'Neil, followed them around.
