For the first time in the series, Ferb says Phineas' name and uses his stepbrother's catch phrase. "Phineas, I know what we're going to do today!"
This is the first time we see Lawrence's eyes without his glasses.
(After Phineas and Ferb help Dad practice a number with synthesizers)
Phineas: Primo, Dad. I think you're ready for the big time.
Lawrence: Correction. I am ready to have once been part of the big time.
Songs: I'm Lindana and I Wanna Have Fun! and Alien Heart.
