Every Groovy Girl likes them for different reasons - Gwen loves their musical style and the instruments in their songs, Oki and Reese are all about their voices and swoon-worthy harmonies, Vanessa and O'Ryan love their sense of humor...and of course, Yvette loves them because they're cute.
They first appeared in the Season 2 episode "Yvette's Got Talent", but as only their voices and on Yvette's posters.
