| File:Xylemite 1 Annoyed Icon.png | Grrrogg! Someone sent us a meme ranking Marble Cinematronic Universe heroes and it's totally wrong! |
| File:Xylemite 2 Surprised Icon.png | Airshot is ranked first and Magnesium Man is eighth?! What kind of edgelord idiot does that?! |
| File:Xylemite 1 Confused Icon.png | And who is that in the background of this screenshot from the movie? |
| File:Xylemite 1 Confused Icon.png | Is that Xylem? |
| File:Xylemite 2 Sad Icon.png | "Xylem" is the name of our planet, our species, and our leader who disappeared a few years ago. |
| File:Xylemite 1 Sad Icon.png | We're not very good at coming up with names for stuff. |
| File:Xylemite 1 Annoyed Icon.png | Out missing leader looks like he was a background extra. |
| File:Xylemite 2 Happy Icon.png | Low pay but access to the craft services snacks. |
| File:Xylemite 1 Annoyed Icon.png | Snack time is over. Fire up the teleporters, we're going to this "Springfield" to get our leader back! |
| Meanwhile on Earth... | |
|
Ah, tree sap. |
|
Hey, Xylem, what's wrong? |
|
Since all plants are psychically connected, my roots sense my subjects on Xylem are coming to get me. |
|
Maybe hiding as a background extra in that Marble superhero movie was a bad move. |

| File:Xylem Disguised Icon.png | *snooty laugh* I am zee famous French director, Pierre Le Plant. Who ees zis "Xylem" of whom you speak? |
|

|---|---|
| File:Xylemite 1 Confused Icon.png | Hey Xylem, what's with the beret? |
| File:Xylem Disguised Icon.png | "Xylem"? Je ne connais pas ce Xylem dont tu parles. |
| File:Xylemite 2 Annoyed Icon.png | Knock it off, Boss. We know it's you. |
|
|
Damn. There goes hours of online classes with Rosetta Stone. |
|
Hey, why are you creeps hassling that poor French guy? |
| File:Xylemite 1 Annoyed Icon.png | He's not French, he's our leader, Xylem, and we're taking him back to Xylem. |
|
Taking Xylem back to Xylem? I'm confused. |
|
|
Does someone want to explain the name thing to this guy? I can't do it anymore. |
The Horror Happening, Pt. 3[]
Start[]
| Character | Dialogue |
|---|---|
| File:Xylemite 1 Confused Icon.png | Xylem, why have you been hiding out here? |
|
A lot of reasons. Mostly they have these treats called "Donuts" that are amazing. |
| File:Xylemite 2 Confused Icon.png | Why don't we just crush these primitive Earthlings and take all the donuts we want. |
| File:Xylemite 1 Annoyed Icon.png | Seriously. How hard could that be? |
|
Here we go again. We are NOT having another Halloween ruined by dinosaurs or alien invasions or whatever this nonsense is. |
|
Yeah! We want ghosts or real monsters – something that's actually scary! |
| File:Xylemite 2 Annoyed Icon.png | But we're sentient alien plant invaders. It doesn't get more horrifying. |
|
I've picked scarier vegetables out of my teeth after dinner. |
|
Don't lie to them, Homer. You don't eat vegetables, and you know it. |

|
|
Okay, that's enough. You guys want something scary and monstrous? Wish granted! |
|
Happy now, Bart? |
|
Eh, what's the worst a bunch of plant guys can do? Force us to water them? |

Alright, herb-a-bores. Tell me how you're going to conquer Springfield before I let Otto smoke you. |
|
|
We won't fight. Instead, we've animated the most powerful of your local flora to do it for us. |
| File:Mighty Oak Leader Happy Icon.png | Behold! I am the mighty oak! |
|
|
You've got a squirrel on your branch? |
| File:Mighty Oak Leader Scared Icon.png | Get-it-off-get-it-off! |

They are no match for us. Mighty Oak, squash these guys! |
| File:Mighty Oak Leader Happy Icon.png | I'm on 'em, boss! *steps on Xylemite* |
|
|
Not us, you idiot! The humans! |
| File:Mighty Oak Leader Annoyed Icon.png | Clearer directives would help. |

| File:Mighty Oak Leader Annoyed Icon.png | Shut your knot hole. |
|
|
*gasps* |
| File:Mighty Oak Leader Annoyed Icon.png | Everyone stop talking, laughing and running around. |
|
This is turning out to be the most boring Halloween ever. |
| File:Mighty Oak Leader Annoyed Icon.png | You'll all remain perfectly still, or you'll get stomped. |
|
Now that we're not allowed to move, I really need to go to the bathroom! |

| File:Kung Fu Werewolf Annoyed Icon.png | Hey, Taekwon Drac, look at this crazy meme ranking heroes in the Marble Cinematronic Universe. |
| File:Taekwon Dracula Confused Icon.png | I don't want to see any stupid rankings. |
| File:Kung Fu Werewolf Icon.png | They have you twelve spots lower than Airshot. |
| File:Taekwon Dracula Annoyed Icon.png | What?" Gimme that! |
| File:Taekwon Dracula Annoyed Icon.png | Where was this sent from? |
| File:Kung Fu Werewolf Confused Icon.png | Some place on Earth called "Springfield". |
| File:Taekwon Dracula Annoyed Icon.png | Gather the rest of the monsters. We're going to this Springfield. |
