Shell Shocked

(Wouldve put 'crossover' but Mr. Peabody and Sherman wasnt an option) Sherman runs away from Grunion only to meet four mutant talking turtles. Sherman grows close to these turtles and considers them as brothers, and is trained in the art of the ninja. Sherman now faces a new threat to his new brothers, his father, and his life. Collab with Shinigamilover2 (Rated T just to be safe)
