Laura gets a bad score on the math test. Afraid she won’t be able to go out with Kana, Laura lies to her Mom and says that she got a perfect score on her test. In the meantime, the Ham-Hams encounter a strange new hamster…Nin-Ham, the ninja hamster from Iga Iga Valley. In anticipation of having Nin-Ham teach them some ninja moves, the Ham-Hams prepare Nin-Ham a huge feast! Nin-Ham doesn’t want to admit that his grades were so poor that he didn’t actually pass ninja school, so he shows the Ham-Hams some pretend ninja tricks.
