Ren and Stimpy are sleeping in bed. Suddenly Stimpy's eyes pop open. He makes confused sounds as he throws the covers off himself and walks into the bathroom. Once in, he takes out a hammer and puts some Catnip Toothpaste on it, and proceeds to "brush" his teeth with it. Then, he drinks some Dog Shampoo and gargles it, with the broken teeth still in his mouth. He then swallows it all. Then, a hair pops out of his nose. He pulls out a saw and saws off half his nose, but the hair is still there. Ren pops in and says "Hey! Can't you wait until morning to saw your face off, just like everybody else?"
Breakfast table. Stimpy is cooking breakfast.
Ren: (Sniffs) Boy, that bacon sure smells great!
The camera zooms over and we see Stimpy is cooking his own tongue in the frying pan.
Ren: Mmm, I can almost taste it right now! Doesn't that.... just... look... great...
Stimpy puts his tongue and his eyeballs on Ren's plate so they look like a smiling face.
Stimpy: (Slurred becuase he now has no tongue or eyes) Breakfatht ith thurved.
Ren screams and almost has a heart attack.
Outside of someone's house.
Ren: All right, that's it! You're gonna see a doctor!
Ren looks at a card he has. It says "Dr. Brainchild. Brains fixed cheap. 303 Cobb Str." Ren rings the bell, someone answers.
Ren: Hello, Brainchild's mom ma'am. We're here to see the doctor.
Mom: Well, aren't you boys sweet? You'll find junior in the garage playing with his toys.
They walk off. The camera pans up and we see Mrs. Brainchild has a large, pulsating forehead, a single red eye, and one malformed arm. She says "I swear, kids get weirder looking every day..."
Ren pushes a button on a trapdoor of the garage door, it opens and they walk in. Stimpy is babbling constantly. Ren walks until he suddenly stops and looks forward. A door opens and we see something coming out. It's Dr. Brainchild. He looks like a kid except he has pale gray skin and a lightbulb on top of his head. He also seems to be sitting on a unicycle that runs on a combustion engine, though it appears to be attached to him. He moves up to them.
Ren: Wow! Get a load of that head!
Brainchild: Hmm.... anthropomorphoids... interesting... (Suddenly Dr. Brainchild has a spasm as the lightbulb on his head momentarily flashes.)
Ren: Doc, could you have a look at my idiot friend here?
Brainchild moves to Stimpy.
Brainchild: Hmm, it does look serious. Have a seat.
Stimpy: (As Mr. Magoo) Why, certainly dear.
Brainchild: Let's have a look at his brain cavity.
Stimpy sits in a seat with his butt in the air and his face near the floor. A scanner attaches to his butt.
Brainchild: No activity.... Stimpy's lack of brain activity can only lead to one thing.
Ren: What's that, doc?
Brainchild: Death, of course. (He whirls around) You'll have to go investigate... inside Stimpy!!! Lightning flashes.
Ren: Me?... Inside him?
Brainchild: Yeeeessss.....
Ren: Are you going to... shrink me?
Brainchild: Don't be ridiculous.
Brainchild pulls out a bicycle pump and shoves it into Stimpy's bellybutton. He pumps along to the tune of 'The More We Get Together' as Stimpy inflates to an incredible size.
Ren is near an ecalator. He has a suitcase. Brainchild is wearing a grass skirt and playing a Mandolin. There are two macho men near who each put a Lauo (or however you spell it, the flower necklaces) on Ren. Ren steps on the escalator.
Brainchild: Don't forget to write, Ren. (He has another spasm)
Ren: I'll send you a postcard. (He looks forward, and has a look of shock)
As it turns out the escalator goes right up Stimpy's... uh.... you can figure it out.
Pitch black, we hear Ren say "Cripes, it's dark in here. Now, where am I?" Ren lights a match and looks around, we see a sign that says "Caution: Explosive Gas". The camera shows a large shot of Stimpy, we hear an explosion and his butt gets a lot larger, then deflates down. Back in Stimpy, we see a nearly skeletonized Ren holding a burnt out match.
Ren is walking through a bus station (the walls are made of flesh, of course).
Brainchild (via radio, we see he has a microphone with a cord leading up Stimpy's butt): Big Dipper calling Uranus 12, do you read me? Proceed through the internal organs via the brown line!
Ren: That's a roger, Big Dipper.
A train pulls up in front of Ren, all the cars are shaped like sausages. He gets on. Ren is sitting next to a corncob. He stares at it for a second, then looks at his paper.
Corn: Hey! What are you looking at? You think you're better than me just because you can be digested? Well you ain't!
There is a penny next to him, who says: You bet your sweet butt you ain't!
Corn: Uppity little punk!
Penny: The nerve of some people!
Announcer: We are now arriving at the stomach.
Ren (deliberately): This is my stop, so I will get off!
Announcer: Come on, let 'em off folks.
Corn: Go on, get off!
Penny: We're riding to the end of the line!
Ren approaches the stomach. It has a neon light-up sign where the word 'Stomach' appears letter by letter with a beep, then a burp as an underline appears below it. A horde of various creatures are approaching.
Brainchild: Proceed with extreme caution. Antibodies may be present, and they are programmed to destroy viruses and foreign matter.
A green lumpy guy with a sheriff star and hat is at the entrace to the stomach. He says: Well, y'all come on in! It's Tuesday night, viruses get in free!
Ren enters. Lots of weird creatures are seated at various tables.
Ren: Bumpkinism, pure bumpkini-
He pauses as he sees the backside of a beautiful woman at the bar. She turns around and actually has two large black and red eyes, and this weird sucker mouth. She and Ren go to each other, and start to kiss, but the creature has such a large mouth it sucks Ren's skeleton right out of his body. Ren collapses into a puddle on the floor.
Ren: (Watery) Oh, baby! What a woman!
A sign appears that says "One year later"...
Ren is sitting near a fire in a chair with a fez and a pipe, the thing from the bar is in a rocking chair nearby knitting something. Ren has several small ameoba like creatures on his body. One pulls it's mouth off him and says "Daddy, tell us how you and mommy met!"
Ren: Well, junior, it all started about a year ago when my pal Stim.... STIMPY!!!!!
Ren jumps up and runs off.
Brainchild: You should be approaching the pharynx, Ren.
Ren climbs up and enters Stimpy's nose.
Ren: Light! I can see light!
We see Stimpy's nostrils in the distance, Brainchild is seen through one of them with a megaphone.
Brainchild: YES! You're in the sinus cavity! Be on the lookout for sudden floods of... backwash!!!
Ren: Backwash?
Suddenly Stimpy snorts and a huge wave appears next to Ren and crashes down on him. He struggles around until one of Stimpy's boogers shouts "Here man, grab my goblin!" Ren grabs and hagns on for dear life. The booger shouts "Hey man, take it easy!"
Stimpy starts picking his nose and Ren gets stuck on his finger. Stimpy opens his mouth and looks like he about to eat Ren but shoves Ren into his ear instead. Ren picks himself up and sees a sign that says "Stimpy's Brain <==".
Ren: Ah, the passage to Stimpy's brain!
Ren runs through the tunnel, but there's a gust of wind and a swarm of bats. He gets to Stimpy's brain.
Ren: I can see the problem! Stimpy's ignorant gland has a stranglehold on his brain!
We see a large pink oafish organ holding onto Stimpy's brain and punching it while laughing stupidly.
Ren: Hey, you big dope! Let go of that little dope!
Stimpy's ignorant gland drops Stimpy's brain and turns to Ren.
Ren: Why don't you pick on someone your own size!
Stimpy's ignorant gland wasn't small, it was just far away. It steps up to Ren and is like 5 times his size. It grabs him and starts beating the crap out of him.
Brainchild: Congratulations, Ren, your mission is a success. Stimpy's brain activity is resuming.
Suddenly an alarm goes off and Braichild pulls out a watch and says "Uh oh..."
Back in Stimpy's head, Stimpy's stupidity gland is still beating the crap out of Ren. The Telegram Monkey (Who is a recurring character, always delivering telegrams) rides up on a bike and says "Message for Ren Hoke."
Ren: That's Ho-ek. Read it for me, will ya, boy?
Monkey: Sure thing pal. To Ren: Stimpy will deflate in five seconds. STOP! Run for your life. STOP! Best wishes, Branchild. (No spelling error, he says Branchild like oat bran)
Ren: Thanks. (He flips the monkey a coin)
Monkey: Uh-huh. (He drives away)
Ren: Now, uh, where were we? (Stimpy's ignorant gland raises its fist and closes one eye.) FIVE SECONDS????
Ren tries to run away, but there are organs falling everywhere.
Brainchild: Five... four... three... two... one...
Brainchild darts away as Stimpy 'pops' and all the helium goes out his butt as he flies around the room like a balloon.
We see a television set. Someone on it is saying, "The baby's college money is missing! Did you take it???" It pans over to Stimpy who says "Ha ha, funny!" He takes a sip of a soda, and we hear Ren's muffled voice saying "Hey, Stimpy, how about a slurp of your soda?" Stimpy says "Sure thing, pal!" and sticks the straw in his nose and slurps of soda move through it. It pans out and we can see Stimpy has a large Ren shaped lump on his head.
