Subscribe to never miss a Film Theory! ►

It's been a while since we talked Phineas & Ferb, so I knew I needed to check in to see if there were any new theories being concocted in that backyard. It turns out, there totally IS! Today Theories, we are talking about the killer plant from SPAC! In the 'Phineas and Ferb the Movie: Candace Against the Universe' we come up against an alien species that needs something from earth. Theorists, that is just the set up to a KILLER theory!

    plants can breath too, they absorb O2 and release CO2 just like most of multicellular organisms, so that is the easiest explanation to this whole theory...

    Fun fact: Dan Povenmire, the show's creator, has confirmed that the brothers got their funding in the first episode. When the rollercoaster is almost done, Phineas looks at Ferb and said: "We should've charged more". Dan then stated that they took that money, invested it wisely, and that's how they got their money Here is the source
