Pure fun, and nothing like Naruto

This show is actually quite different from Naruto, apart from being about a ninja school. While Naruto has a series-long plot, with characters developing and a lot of fighting, this is just meant to be funny to kids. It is not violent (while Naruto, at times, is) and it doesn't have much fighting by design - it's rather about challenges, teamwork and throwing / jumping on any kind of object. Characters are very cute, graphics are gorgeous and most of it is drawn in a funny sort of super-deformed style.

For younger kids and for adults relaxing it's just adorable, then if you're in that cocky age in which you need to watch people just punching each other on their faces, go watch Naruto instead.
