Phineas and Ferb, you are so bust... Oh, my gosh, where'd it go? You there, small children. Where's the big contraption?
Isabella
I don't know. It was here just a moment ago.
[to Stacy]
Don't you realize what this means?
Stacy
We're done.
No, a mysterious force always takes away Phineas and Ferb's inventions before Mom shows up. This time, it took away their invention before I showed up. The mysterious force recognizes that I'm now a grown-up.
Stacy
A mysterious force? Really?
