TMNT-2003

It was a average day in their lair. Each brother was doing their own thing. Leonardo was training, Raphael was punching his punching bag, Donatello was working on some gadgets, and clasic Michelangelo was watching TV. Suddenly they heard weird noises farther in the sewers. They went to investigate. Upon entering where they heard the noise, they saw a glowing green portal. They prepared themselves for whatever or whoever would enter through.
