I improvised a translation... it's incomplete and not especially good, but It might help you get an idea of what this short is about:
Narrator: Carlos is a normal guy, with a normal life. Every morning... uh.... every afternoon, around five, he wakes up to start his day full of energy. He turns on his computer and starts nourishing (?) with cultural information and news.
In the end, he even embarks on a new adventure... killing monsters from Final Fantasy XIII.
But this isn’t his story.
WATER MIND
Eustaquio: There’s lots of different kinds of neurons in the brain, with predetermined functions. But I’m special. I’m unique. I’m... THE CHOSEN ONE.
Mother: Niño! (literally, "kid or child") NIIIIÑO!
Eustaquio: MOM! I’m recording my log!
Mother: ("Qué bitácoro ni qué bitácora" is a sterotypical "mother sentence" in wich she enumerates the thing and she then changes the gender of the thing in question, to dismiss it's importance.) Have you seen your room? Tidy up or you’ll get no dessert!
Eustaquio: *sigh*... Being the chosen one is very hard... I hate it that people stare at me on the street. I hate that people stare at me at the office... and I hate not being able to share my electrons! But I’ll take matters in my own hands...
Narrator: And this is how Eustaquio started his voyage to...
Mother: NIÑO! Niño, Take a sweater, it’s getting cold! You’ll catch up a Pneunomite ("Pulmonitis", mixing "pulmonía (peumonia) with the sickness ending "itis")!
Eustaquio: I’m going to die... Outside from the city, this brain is only desert... Only the burning sun will see me die... and maybe a ROLLING PLANT (??) contaminated by the internet and videogame plague that affects this brain...
I raise my eyes to the neocortex hoping that my sacrifice will be remembered... oof!
Let’s see if there’s somebody here that can help me..
No, not this guy, uuuh, aaah... THIS ONE ¡OOOOOOOH!
Trucker1: Woah, what a chick!
Trucker2: With that ass, I’ll invite you home to take a crap!
Trucker3: *Snorts*
Eustaquio: mmmh, what have we got here?
Waitress: Welcome to Plasmid Bar, what can I do for you?
Eustaquio: What you can do for me is very simple. You...
*Stomach roaring*
You may get me... something to eat...
*Eats*
Eustaquio: Baby, get me the bill.
Waitress: It will be an Oedipus complex and 50 cents.
Eustaquio: *GASP* WALLEEEEET!
Bar guy: That sounds like you can’t pay... And we don’t like bad debtors (?) here... You’ll...
*ALARM*
Bar guy: Everybody to the shelter! NOW!
Eustaquio: What? What’s happenning??
Bar Guy: I said “TO THE SHELTER!”
Eustaquio: Aaah!
Bar Guy: Kid, did you want to die?
Eustaquio: no...
Bar Guy: You must know there’s a terrible tumor out there!
Eustaquio (thinking): These people live in fear of a tumor? It seems what they need... IS A HERO.
(talking) HEEEY! I’LL TAKE CARE OF IT!
Eustaquio: Log. I’m approaching the beast’s lair, armed just with my wit and a gun with silver bullets covered in garlic with a center of strawberry chewing gum. It’s very dark in here, so I must be very carefu... ¡AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!
What is th... AAAAH! A DEAD BODY! AAAAAAAH! It’s getting near! It’s getting near! AAAAAH!
Tumor: *Giggles*
Did I scare you?
I’m a very bad tumor!
Eustaquio: Tumor! I’ve come to end your reign of terror!
Eustaquio:... I can’t...
Tumor: Boo!
Eustaquio: Ah!
Narrator: Eustaquio discovered that Benign, the Benign tumor, was not bad. They made a deal. He wouldn’t leave it’s lair and he’d bring him food. With a piece of membrane, he came back to the bar like a hero, giving his first step to the path of glory. And this is how begins... the story of the Water Mind!
