What music video is that features a subgroup of Morning Musume?

Question:

I think it's a subgroup. It's like 3 chicks dancing a groovy dance the ENTIRE video and it's like upbeat and fun-ish. The chicks are hella young. Probably 18-21. I saw it a long time ago and I liked it.

Anyone remember?

Answer:

One of the sub-groups was called Mini-Moni. Do a search on Youtube for that name and you'll find a bunch of videos.
