Summary
This story takes place in an alternate universe, where Stacy recognize Monogram's voice and Carl's name, which lead to Candace finding out about Perry's secret spy job and discover the Secrets of the Mysterious Force
I just watched the episode "Entrance Exam", and it was great. Though if it had changed the formula a little bit, it would've been better.
Okay just hear me out, what if Monogram pressed the wrong button and let in two teenage girls in the lair.Now because Phineas and Ferb are gonna go on hiatus again i figured i'd try a long fanfic to still enjoy the story.
If you haven't watch the episode yet i highly recommend you watch it first.

If there was a prize for being the second best for everything, Stacy Hirano would’ve won it. That happened when your little sister was Ginger Hirano and your best friend was Candace Flynn. She knew she wasn't anything particularly special, and she swore she was okay with that.
