Isabella "Motseralla" Gonorrhea-Sharpero - An annoying brat looking for an excuse to annoy Phineas and Ferb. She is in the Fireside Girl scouts and has a crush on Phineas, but finds it hard to kiss him without getting stabbed by his nose. Oh, and she's also Jewish. She also hates things cuter than her, like puppies, babies, and cute forest animals. Isabella also can sound like a man, and when she does the man voice, her mouth is so wide, she could swallow a guy. She once did too!
