Ninja students' adventures are a kick for kids.
Parents need to know that this cartoon series features racially and socio-economically diverse characters who treat each other and their elders with respect. Themes of friendship, loyalty, and teamwork dominate each episode, and the students are, for the most part, patient and diligent in their learning. The show includes facets of martial arts training -- including kicking, punching, and throwing ninja-specific objects -- but most one-on-one exchanges have very little contact and few end in visible injury (and any injuries that are incurred don't last long).
