This is a TV show about the Groovy Girls which is in no way related to the "Sleepover Club" books. It is fictional, and created by WatermelonSunshine.
It was on the air from 2004-2008 but it's still popular, due to it re-running on Nicktoons ever since 2009. Its premiere date was on October 2, 2004 on Nickelodeon, at 5:30 PM just after a Spongebob marathon and right before an All Grown Up marathon. It ended on June 20, 2008, but now it airs on Funhouse Network due to Nicktoons pulling it from its schedule on May 10, 2015 alongside Fanboy and Chum Chum (which returned on July 11, 2015), Robot and Monster, My Life as a Teenage Robot (which returned in January 2016), El Tigre (which returned in October 2015), Oggy and the Cockroaches, and Rabbids Invasion (which returned in October 2015).
As of June 2015, Funhouse Network is currently airing it in reruns due to Nicktoons removing it. Nicktoons will not be re-running it anytime soon due to Funhouse Network massively promoting the series.
There were 4 seasons and a total of 75 episodes. Seasons 1-2 featured the Main 6 in their first styles from 2004, while Seasons 3-4 featured them in their second styles from 2006. It was a 2D CGI (a step up from Flash-animated) animated show. The show was about a girl named Gwen and her club, "The Groovy Girls", as they dealt with the ups and downs of their life in 5th grade, inspiring girls to follow in their footsteps and deal with life's ups and downs, and was sponsored by KidsHealth, the #1 most-visited online children's health website. It was created to entertain tweens, especially girls. The girls live in the fictional, seaside city of Glitzville.
The show features well-known voice talent including Candi Milo, Nika Futterman, Chiara Zanni, Jeff Bennett, Carlos Alazraqui and Grey DeLisle.
