In the 2000's Japanese pop group Puffy Ami Yumi had their own cartoon show on Cartoon Network called Hi Hi Puffy Ami Yumi that featured the group going on tour and having fun adventures and while Puffy Ami Yumi did not provide the voices of their animated versions of themselves Hi Hi Puffy Ami Yumi was a fun cartoon and one of Cartoon Network's most popular cartoons in history

It was charming.

Hated it. Their lasting legacy is the Teen Titans theme.

Hi, Bestie! That was a great cartoon! Are they still together? I think the harajuki girls were a copy of them, do you? I wish they would rerun it!
