  • News report: millions of people died because some EEcloner said that you are breathing poison Me: am breathing right now and am not died yet

  • Dr. Doofenshmirtz's mentor wanted to set fire to he sun. Although laughable at first, could that actually cause havoc to planet earth?

  • Then, candace could've just peed on mama plant to make it grow.

  • this was a stellar movie, don't knock it.

  • I love how Mat doesn't use any "This is common knowledge" explanations and discusses everything at full length since I'm pretty sure we all know what photosynthesis is and what air is made up of if we paid attention to middle to high school science. Him explaining to us about all this really does make him a good researcher.

  • So what was the poison people are breathing exactly?

  • Candace was never relatable. She was a nosy snitch who wants to get them in trouble. She doesn’t do it cuz she is fearful of their safety since she goes along with some of their plans plus is aware that their dad and other adult figures knows. And she doesn’t want their mom to know because she’s proud of them except for that episode they put her face on Mt Rushmore. Candace needs to get her own life lol

  • You were the chosen one. You were supposed to help the plant not do nothing. Give the plant nitrogen not carbon dioxide. You were my sister candice I loved you

  • Theory: Dissecting Murphy's law in Milo Murphy's law

  • Maybe they invaded for the mushrooms. All the mushrooms might be dead or something.

  • I learnt this through jjba part 6

  • I've never sen ferb talwc

  • I feel like the movie didn't understand Candace. In my mind, she was never jealous of Phineas and Ferb. She was scared for them. In multiple episodes, but most notably Perry Lays An Egg, it's shown that her maternal instincts are dialed up to a 7 (and that's on a scale of 1 to 5). I always thought she tried to bust Phineas and Ferb because she was terrified one of her brothers would hurt himself.

  • It was weird that they Made a new movie witout anoucing it

  • Subscribe to film theory please pin me

  • 1:46 MatPat I am about to strangle you

  • so pucci was dead dead with that 100% oxygen

  • I learned this in my science lesson Not the movie the plant thing

  • Roblox and Vroblok

  • On the game one can you do little nightmares please I think that would be fun to watch

  • This is why I got Disney plus


  • 4:12 Super Super Big Doctor realized she was the villain, she never recovered

  • hold on mat pat, were did magnesium get dipped out of the mix 8:49

  • you know that plants respire too and produce carbon dioxide themselves

  • actually, when the first few cells entered the earth's atmosphere, they were photosynthesising which means they consume CO2 and give out O2. when oxygen concentrations were too high it became toxic, which through evolution resulted in cells that respire aerobically

  • Please do a milo Murphy's law theory

  • FILM THEORY IDEA:pls do a THEORY on fanfictasia by artspear entertainment

  • When I was little I used to hate Phineas and Ferb cuz the Brothers doesn't get busted by their mom

  • Oh my god the villain is literally queen wasp, *oh my god it’s happening*

  • Did anyone else know that this existed? Fanders: Yes.


  • I thought plants need oxygen at night

  • The Roblox cluster wow they play a lot of that game don’t they

  • RoBLOK

  • You should watch milo Murphy law cause I just feel like its completely filled with theories

  • actually technically oxygen is poison to anoxic creatures so yeah matpat ur right

  • Can we get a Chalkzone theory video pretty please🤔

  • When you said co2 was not that common on earth, I immediately thought nitrogen, and what do you know, I predicted it

  • We have chetos as industrial waste we absolutely love... Now we have oxygen as industrial waste, huh?

  • She is the chosen one because she brought the aliens to earth

  • 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?!?!?!?!?!

  • I love the game roblox

  • The mushrooms of fleebleoot aren't actuall mushrooms. It's not earth so they aren't mushrooms. We can't compare earth and fleebleoot mushrooms. So as far as we know the don't work like our mushrooms.

  • Did you know that this just a kid moive and a kid show and a kid game

  • 0:11 shhhhhhh I was not ready to be called out like that

  • I mean if the planet has aliens that breathe and expel oxygen it can be the same with mushrooms

  • Didn't tell us why we were breathing poison

  • We want more of PaF theories

  • Yes, I know that high concentrations of Oxygen is, in fact, dangerous for your health. I read Jojo's. I have a Johnny profile for pete's sake

  • feebla oot

  • Matpat: ''Mushrooms aren't green'' Death cap: ''Am I a joke to you?''

  • what about their radar where they find carbon dioxide? is it just malfunctioning

  • "Big mood Candas, big mood"

  • I just want to say thanks for putting Funguy from Chrono Cross into this video. That's my all-time favorite game.

  • “She can control people through a plant” Me: *Wings of Fire arc 3 flashbacks*

  • Me looking at the thumbnail: The result of pcs crossbreading

  • Omg me and my partner watched it like Two weeks ago!!!

  • Jo

  • omg, I caught that Chrono Cross reference!!!

  • Feed me Seymour



  • If Aliens have different properties then can't Alien Mushrooms have different properties too?

  • You should make a channel called health theory and the logo should be a heart

  • How do you know those are mushrooms? What if Super Super Big Doctor mixed up the translations? "I THINK in your language it's called carbon dioxide."

  • 0:33 / 11:39

  • I thought you were kidding about that the movie was a thing ):

  • Matpat: You're exhaling H20 when you breathe out ME: What????? Vomit?????

  • I watched this, don’t understand how it got 100% rotten tomatoes.

  • I love it i watched it when it frist came out

  • 2:20 wacey twist!!!

  • “Did anyone else know this existed? Yeah me either” Me: I did I was waiting for it. Wait...MY life must be so boring to wait for that movie. :(
