Abigail Lavenders is a new character in Phineas and Ferb: School Dayz!. She is a student at John P. Tristate Elementary. She's kind of a mischievous, rule-bending kid who always goes sneaking around, doing things she knows she should'nt do. She has a knack for doing those things without getting caught. Abigail doesn't really do this in order to cause chaos or pull any kinds of pranks or tom foolery. Mainly, she does this because she feels somewhat trapped, and wants to have some freedom in her life. Abigail's parents sort of treat her like a "Bubble girl" and always tell her what to do and forbid her from going a lot of things. She's annoyed by this and just wants a little independence. She hangs out with Phineas and Ferb because they are perfect at doing things like that.
