Joanne and Maria are Phineas and Ferb's evil (girl) counterparts from New York City. Once Joanne and Maria we released from jail, due to the fact that they had injured various people, their parents (and step-parents) decided they would not let them stay with them. So, they decided to put them up for adoption in Danville (when they were on vacation there). Isabella's family decided to adopt Joanne and Stacy's decided to adopt Maria. After a few weeks, Isabella get very mad at Joanne when she tried to flirt with Phineas. "You evil, little brat! Get your but outta here"
