Strong Inferior Minds

Neuro-Adolescent Degeneration.

If you ever thought of a zombie apocalypse going on, it's more likely to be a pandemic of a dangerous disease. A zombie apocalypse would have zombies roaming around and biting people so they can turn into zombies as well. A pandemic is a disease that sends an area to lockdown in order for it to not spread.

Gumball: *walking down the hallway* Pizza for lunch? That's pretty rare!
Darwin: Let's hope it isn't trashy pizza! Hahaha!
Idaho: Hey guys, hey guys! *approaches them* Did you know that pizza originated from plants??
Gumball: Pizza isn't a plant, Idaho. It's a man made food originally from Italy.
Darwin: Though its crust was made from Italy, that's what I knew from history class!
Gumball: Stuffed crust pizza?
Darwin: No, dude! Original crust!
Idaho: That's what I was trying to say!
Gumball: You should have said it in good detail, not in your old country way! Hahaha! *walks to the buffet area along with Darwin*

Pizza isn't poisonous and wouldn't start a horrible pandemic. If anything, pizza is the most delicious fast food thing I have ever had in my life. There's no way it would poison someone to the brink of peril.
But when you think about it... A week ago, someone passed out at the playground because they didn't have enough sugar in their system. So it would have been pizza causing a sugar rush or something like that. But Mr. Cornielle said that they were lacking sugar in their system. It felt more serious than saying it was a simple malfunction.

Penny: Hi, Gumball! 
Gumball: Hey there, Penny! *sits down beside her*
Penny: *kisses him on the cheek and smiles*
Tobias: Ohhh, look! *walks past by them* The couple's being annoying for the hundredth time!
Penny: It's called true love, Tobias. What you always do to the girls isn't true love.
Tobias: Oh, it is true love! Watch this! *goes to Carmen and grabs their box of juice* Hey, girl! How's it ha- *abruptly stops talking dropping his plastic cup*
Darwin: Gonna show your ways of love, Tobias? Or are you too embarrassed? Hahahaha!
Tobias: *doesn't respond and stays frozen stiff staring into the void*
Gumball: Uhh... Tobias? Aren't you saying anything?
Carmen: Tobias, are you okay?
Tobias: *is still silent and has an expression of strain*
Carmen: *speaks in a firmer tone* Tobias, are you okay??
Darwin: I think he's messed up his line, hasn't he?
Gumball: No, it's not that he messed up his line- He's literally not re-
Tobias: *eyes roll backwards and sighs fainting onto the floor*
Gumball: TOBIAS!!! *stands up from the booth and sits on his knees looking at him* Tobias, what happened??
Darwin: Dude, he just passed out!! What just happened!? *approaches him quickly sitting on his knees as well*
Rocky: What is going on there? *leaves the buffet area and approaches the crowd of students*
Carmen: Hold on! Let me check if he's breathing or not!! *tries to lean her head on his body but gets pulled back by Masami* Ahh!
Masami: Carmen, your thorns will hurt him!!
Gumball: Tobias!! *shakes his body frantically* Wake up!! Wake uuup!!!

It isn't surprising, knowing that Tobias was the first one to die in this school. People thought it was the pizza poisoning him to the brink of death because usually the school lunch was not so good at some days. But it wasn't that. Carmen said that his eyes were glowing blue for some reason. She doesn't know if she was seeing things or not, but that's her being honest. So who knows.

A month later...

Almost half of the students in school were dead from the same situation. I've always questioned why I was still alive along with Darwin, Penny, and Anais.
When the deaths happened, the staff was banned from bringing up that one disease named from the first kid who died from this disease. Pretty sure it was called Evelyn's Disease, but someone gave it a proper name; Neuro-Adolescent Degeneration, or better known as N.A.D.. This disease happened within kids and teens, so the name makes sense.

Miss Simian: Today we'll be talking about Earth's gravitational pull. Everywhere in the Earth, even when we are facing the dark night sky, there is still gravity pushing us down.
Gumball: *writes down on his paper*
Darwin: Ugh, I broke it again... *grabs another pencil from his pencil pouch and throws the broken pencil to the trash can*
Gumball: *sighs tiredly and lays his head on the desk crossing his arms*
