Fireside Girls Fight a gorilla(Fireside Girls 2)

Isabella told the fireside girls that they haven't fought a gorilla yet, so they take a field trip to the gorilla brawl stadium, their way of taking down gorillas is by killing them, might be too violent. Phineas and ferb were seen watching fireside news showing off the gorilla brawl stadium since that's where the girls went. meanwhile poofenplotz has been working on a weak-inator that will make things weaker like the fireside girls during their gorilla fight, but pinky fixes it near the end and at the time a "gianter" gorilla shows up.
