the fact that robot riot is a diagenic song (sung in universe not just as background track) implies that love händel just like. had a song about killing robots brutally. they had that on the ready. why.
Honestly when they met Phineas and Ferb they have probably heard from Candace or Linda the things those two have been doing so I'm sure at one point they were like "yeah I'm sure that one day those two are going to end up killing a bunch of robots" and they decided to make a song just in case. Like by then in the tri-state area nothing it's too weird for them
