The mad dogs

It was a normal night in new York City, Raph, leo, Donnie and Mikey and April and Cassie were roaming the city. They were on their way to Russell park when there was a strange noise. "What was that?" asked Mikey. "I don't know." said Raph. "But it came from over there." They traced where the sound came from, the arrived at a construction site. As the looked around, finding the source of the noise a cement bag was flying right towards them. Luckily, Leo drew out his sword and sliced it in half. Then all the cement became a giant dust cloud. Suddenly, a mysterious stranger was walking towards them in the dust, as the dust cleared the stranger stopped. The stranger was wearing a cloak and mask so no one can see their face. Then the stranger took off the mask and the hood of the cloak. As raph and the others got a closer look it was a girl with purple ponytails, a strange outfit and a purple cloak.
