Happy Birthday, Isabella

I wish for time alone with Phineas.

Phineas and the gang celebrate Isabella's birthday in a big way, but all she really wants is some quiet time with Phineas. Meanwhile, Doofenshmirtz has installed his Bugs Me-Inator onto an evil bug bus and is driving around Danville turning all the things that bug him literally into bugs.

End Credits
Sometime later, Candace and Stacy are spying on the kids. Candace sees Phineas saying "Where's Perry?" and asks Stacy where she thinks the platypus went. Stacy quickly and nervously responds that she doesn't know anything about where Perry goes every day. Candace agrees, wondering why she asked Stacy in the first place; in her mind, Stacy is glad that no one suspects anything.
