Petit Moni (Pucchi is the Japanese way of pronouncing Petit) was formed in 1999 after Morning Musume's first hit, 'Love Machine'.
The group was made to be more energetic and down-to-earth than the other major subgroup at the time, Tanpopo. The original line-up were Sayaka Ichii, Maki Goto and Kei Yasuda. Their first single, 'Chokotto Love', was also a big hit.
However, Sayaka graduated from Morning Musume in May 2000, just six months after Pucchi Moni debuted. Hitomi Yoshizawa was added in her place for the release of Pucchi Moni's next single. They released two singles with this formation.
In 2002, it was announced that Pucchi Moni would again have to be reformed due to the impending graduations of both Maki and Kei. In their place will be Coconuts Musume's Ayaka and new Morning Musume member, Makoto Ogawa.
There has been no further releases from Pucchi Moni since this announcement.
