Nin-Ham (ニンハムくん) is a hamster who stars in a few episodes. He is a ninja-in-training, but struggles greatly at actual ninja skills.
He is not to be confused with the Ninja Hams, a group of similar hamsters that Nin-Ham is not a part of.
Nin-Ham is a ninja hamster who comes from Iga Iga Valley. However, he was not a very good ninja, even failing his ninja test. He decided to leave home so he could be appreciated by non-ninja Hams, in which he meets the Ham-Ham gang. Nin-Ham proceeded to lie to the Ham-Hams, telling them he passed the ninja test, and tried to "teach" them his techniques. However, the Ham-Hams found out he was lying, leading to him finally telling the truth. After learning his lesson about telling lies, the Ham-Hams encourage him to keep training and continue his passion.
