Film Theory: You Are Breathing POISON! (Phineas and Ferb)

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!

    Wait a minute if the people of feebloot (Idk how to spell that crap)just breath oxygen and exhale it back,makes sense since that means a fixed amount of oxygen exsists right?Well matpat said that mushrooms breath oxygen and exhale CARBON DIOXIDE and if there are no plants on feeblaoot then how does the planet replenish its oxygen,answer they don't.So how do they live on that planet?!?!?!?!?!

    Plants don’t have mind controlling spores but the “zombie fungi” or Ophiocordyceps unilateralis does. It mind controls or takes over the body’s of ants and other bugs. It’s kinda scary but you could look it up if you want. :)
