The Bikini Bottom Super Band was a band organized by Squidward to show up his rival, Squilliam Fancyson. The band had only one known performance at the Bubble Bowl. The band was terrible until SpongeBob kept it going and they sang at the Bubble Bowl as a rock band and performed the song Sweet Victory. Most of the main characters and many of the Bikini Bottom townsfolk are in the band.
The future doesn't look very hopeful for the band, because the last episode they starred in was "Band Geeks" and that's the only performance they have done. It is also the last episode the band has appeared in.
