Elizabeth "Lizzie" Moore is a female child, 7 years of age, and is the little sister of one of the show's main characters, Alyssa. Lizzie is loud, obnoxious, bratty, and oftentimes spoiled. She will often lash out if she doesn't have her way, and will pester relentlessly until she does. She cannot be trusted to go outside, as she could get herself hurt or potentially ruin someone's property with her reckless actions. It can get to a point where she even needs to be confined to a leash so she doesn't run amok. And when she starts fuming and gets into a temper tantrum, she pretty much acts like a gremlin, right down to making noises akin to one. She is a huge fan of UNO.

Despite being obnoxious at worst, and precocious at best, she deeply loves her big sister and always wants to hang out with her. She affectionately nicknames her "Lyssie," just as Alyssa and others nickname her "Lizzie". Since Alyssa is busy and juggles many responsibilities, those days where Lizzie can hang out with her are more rare than often.

For her voice, since she is a very young child, something around that high range will work. A voice that can oftentimes be bratty, but also slip into legitimate or deceptive innocence, and obnoxiousness. While, at the same time, showing that she truly loves and looks up to her big sister. We appreciate and encourage if you take a different spin or interpretation to this character.
