Phineas and Ferb: 4x19
Happy Birthday, Isabella
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.
