Can anyone tell me what it is? any people who lived in Japan 15 years ago?

Question

I'm looking for the title of an anime I watched 15 years ago, and for its opening song. It's about the adventures of 3 little ninjas: one wears glasses, another one is a rather good-looking money lover and the last one likes eating and is chubby. They wear blue ninja uniforms (and the girls' uniform is pink). I think it was only released only in Japan. That's all I remember about it. Thx to anyone who can answer!

Answer 1

I'm not from Japan, but can I answer anyways?

I think the show you are looking for is called Nintama Rantarou. Here's some information about it: http://myanimelist.net/anime.php?id=1199
