Marsh and Povenmire wanted to incorporate into the show the kind of humor they had developed in their work on "Rocko's Modern Life." They included action sequences and, with Disney's encouragement, featured musical numbers in every episode after "Flop Starz". Povenmire described the songs as his and Marsh's "jab at immortality", but the pair have earned two Emmy nominations for "Phineas and Ferb" songs to-date. A third Emmy nomination, for the episode "The Monster of Phineas-n-Ferbenstein" (2008), pitted the show against "SpongeBob SquarePants," although neither nominee received the award due to an unspecific technicality.
