There are other Advantage Audio sound effects they created.
Such as a telemetry beep heard in Phineas and Ferb: The Movie, Across the 2nd Dimension (Parry's locket), and heard in the Star vs. the Forces of Evil episode, Marco Grows a Beard.
Also a beep sound used on Fairly OddParents, Phineas and Ferb, and the Mickey Mouse 2013 shorts.
