Advance the plot on your boy's ninja training by purchasing him a trusty Halloween costume and companion outfit for every time he goes outside to play. The Boy's Blue Ninja Avenger Costume is a blue jumpsuit with a tunic. On the tunic are designs that depict a shoulder strap going across the chest and a dragon brooch situated at the center. Your boy will also get a matching blue hood to wear over his head. This hood has a visor cut out on the eyes so that his visibility is not obscured. This costume will be his favorite thing for several months as his interest in martial arts expands. While Halloween will be fun and satisfying, it is all the physical exercise and discipline he'll learn from martial arts that will be the best result to come from this costume purchase.
