Only slightly less hillarious than the first, mostly due to a complete lack of ninja's in leisure suits.
Still a great series.
ALL AGES ( )

What do you do when your very own ninja warrior is threatened by a rival ninja army hired by the most obnoxiously snobby rich kid in your elementary school? Even worse, what do you do, when she starts to channel powers of darkness, and first the school and then the whole town is plastered with posters saying, “Big Sister is Watching You!” Do you really have to ask?

These laugh-out-loud funnies are chock full of verbal and visual humor that will appeal to the fans of Captain Underpants. There’s ninja fighting, a scheming little sister, mind control cereal, silly songs, and even – are you ready for this – disco ninja dancing! ( )
