Hydee and the Hytops
Hydee and the Hytops are an all female pop-rock garage band. Their rival band is an all male heavy metal garage band called The Snake Claws, who are lead by Zeke.

The band is made-up of:

Hydee (lead singer) is the front-woman of the band. She is smart, charming and good-spirited.

Mariko (lead guitar) is a tomboy of Japanese descent.

Samantha (bass guitar) is intelligent and an academic over-achiever.

Charlotte (drums) love shopping, fashion and funnel cakes. She as a crush on T.J. - the drummer of The Snake Claws.

They are unrelated to the cartoon (although, they could be among the many nameless students of the High School).
