Subscribe to never miss a Film Theory! ►

It's been a while since we talked Phineas \u0026 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!

  82. BattlestarGaraptica

    BattlestarGaraptica4 dögum síðan

    Nitrogen is useless in our body. If you look up the chemical composition of inhaled air and exhaled air, you'll notice that the nitrogen levels don't change. But as MatPat said, if there is too much oxygen, human bodies would not be able to handle it.
