Get ready to train with Splinter and learn the ways of ninjutsu when you put on our tween Teenage Mutant Ninja Turtles costumes. Our tween Halloween costumes feature adorable dresses with the same ninja fighter style. Use your smarts like Donatello to beat the enemy or show your courage in a tween Leonardo costume. Do not forget the other fun ninja turtles nunchucks using Michelangelo and Raphael with his sais. You will be ready to take down the Shredder with the help of April O'Neil, Casey Jones, and our tween TMNT costumes this Halloween!
