Shelley is the MC who hosted the Battle of the Bands in the episode of the same name.
She is voiced by Olivia Olson.
As the host of the event, Shelley rushed to get everything organized before the competition. Her impatience was clear as she shouted at the people she was trying to organize and mistakenly assumed Zack's statement that their band was 'just getting started' was actually their band name. In spite of this, she seemed enthusiastic during the event itself.
Shelley is a slender, pale-skinned young lady with brown eyes. Her black hair has a white streak running through it, and it's tied back in a thick black ponytail.
She wears a sleeveless purple crop top and a pair of light blue jeans with visible seams and lighter colored cuffs. Her shoes are black with white soles, and she wears pink lipstick and a number of gold-colored bracelets on her left arm.
In "Battle of the Bands", she acted as Master of Ceremonies for the Battle of the Bands.
“It's Battle of the Bands, I think they'll notice if we don't have microphones!”
“And you are…?”
