[The Story begins with Dipper and Mabel are getting ready to go to sleep. They stretches, yawns, and hops into their bed. Mabel puts on her nightcap, Dipper fluffs up his pillow, and they lays down to sleep. But when she breathes, Mabel notices something was wrong with her mouth. She smacks her lips and opens her mouth. Inside, her tongue is all dried up and a family of hillbilly germs move away because their home has no water. Mabel realizes that she is thirsty, so she gets out of bed to get a drink of water. She walks downstairs and into the living room.]
Mabel: [notices the plant on the edge of the table] Oops. [pushes plant back] Doink. [pours water in a glass and drinks it; but she spits it out after seeing the refrigerator open] I don't remember leaving the fridge open. Huh? Dipper did you forgot to close the refrigerator door?
Dipper: No. [Dipper closes the fridge and sees the living room a complete mess]
Mabel: Huh, I don't remember making such a mess. [spaghetti falls on Dipper face]
Dipper: And I'm pretty sure I didn't eat spaghetti. [;then a big noise from upstairs] Huh? [The noise gets louder and scarier. Dipper and Mabel walks over to the stairs to investigate with a golf club. As they got closer, a shadowy figure comes down the stairs. Dipper and Mabel quivers with fear. But, to his surprise, the shadowy figure turned out to be Soos, who is sleep-walking.]
Dipper: Soos!
Mabel: Oh, hey, Soos. [Soos sleep-walks in the living room] Wake up, Soos! [grabs Soos's trunks, but it slips off her hands] Whoa! [Soos flies through the air, but continues to sleep-walk. Dipper and Mabel attempts to wake Soos up by banging a pot with a stick, but nothing's working. Then Mabel tries to wake him up with an air horn, but nothing's working.]
Mabel: [hops on Soos's head to open his eye lids, but falls off] Whoa! [Dipper grabs his alarm clock, turns up the volume, and sets it to the waking hour. Dipper's alarm clock bellows a loud noise in Soos's face. The noise was so loud that it even woke Stan and several people up. The car alarm goes off and several worms start barking. The alarm clock did not affect Soos and he continues to sleep-walk. Soos sleep-walks into the kitchen, activates a toaster, and splatters butter on it. Then he eats the toaster and toast pops out from his mouth. Soos sleep-walks to the fridge, opens it, and peeks inside.]
Soos: [screams and eats an ice cream carton] [Soos splatters eggs on his buttocks. He walks through the kitchen wall with the fridge on his head. He throws the fridge through the wall and sleep-walks outside. Soos sleep-walks towards the street where an ongoing traffic.]
Dipper and Mabel: [screams and runs after Soos] [Soos sleep-walks across the street. Luckily, none of the car hit Dipper. Mabel goes after Soos, but is almost hit by a car.]
Mabel: [screams and grunts as she gets hit by the car] [The car sending Mabel flying to the other side of the street. Soos steps on Mabel while sleep-walking to another house. Mabel spits dirt out of her eyes.]
Mabel: Soos, no! [runs over to Soos] [Soos sleep-walks to the front door, opens it, and enters inside.]
Dipper: No! [runs after Soos] [Soos sleep-walks across the hallway while Manly Dan are sleeping in his bed. Dipper and Mabel becomes worried that Soos might make a loud noise that will wake him up. Soos sleep-walks towards a collection of model ships.]
Dipper: [screams and turns Soos away from the model ships] Whew. [exclaims as Soos goes to knock over a vase] [Mabel grabs the vase before it fell. Then Soos starts making loud noises in his sleep. Soos continues to make loud noises as the Manly Dan starts waking up. Dipper jumps onto Soos and covers his mouth.]
Dipper: Shh! Shhh! [Soos calms down and Manly Dan goes back to sleep. Dipper slaps Soos's butt and Soos sleep-walks out.]
Dipper: Uh-huh. Phew.
Manly Dan: [turns on the light] What the?!
Dipper: [gets kicked out, screams, and lands on the ground] Ooh!
Manly Dan: AND STAY OUT! [gets stepped on by Soos and sounds like an accordion]
Dipper: Ow! [Mabel grabs Soos's feet and gets dragged] [Green fumes seeps through the air. Soos sniffs it and yawns.] Dipper: [sniffs the fumes] Blech! [the fumes form into a fist and punch Dipper's face] Ow! [The fumes are coming from Old Man McGucket junkyard. Soos goes around the back, enters inside and follows the scent of the fumes. The scent leads to a pot full of old soup leftover from McGucket. Soos grabs the bucket and goes to eat it.]
Soos: Mm. Ahh...
Dipper: No, Soos, no! [grabs the pot] Don't! [Dipper struggles to keep the pot full of soup away from Soos. Soos licks Dipper's head with his tongue, which tickles Dipper and causing him to laugh. Dipper accidentally drops the pot into his mouth and swallows the soup. The soup made him incredibly sick to the stomach and lets out a small, green fume. The fume then makes a skull and breathes into Dipper's face.]
Mabel: [notices Soos gone] Huh? [screams] [Soos sleep-walks into a dance studio. Dipper and Mabel follows, grabs a carton of popcorn, and takes a seat. Soos performs a little dance in his sleep, then sleep-walks off the stage.]
Mabel: Ohh! [claps and sheds a tear]
Dipper: Huh even he sleep walking he still a good dancer.
[Soos sleep-walks out of the dance studio and slips on a banana peel. The peel sends him slipping into the Gravity Falls Carnival!. Soos sleep-walks on the tracks of the Neck Breaker roller coaster ride. Dipper and Mabel flags down a roller coaster car, hops inside and follows Soos through the tracks.]
Dipper and Mabel: Whoa! [Mabel reaches out to grab Soos. The car goes through the loop-de-loop and Soos falls off his pants.]
Soos: Breezy. [Soos falls back into his pants. Dipper and Mabel falls off the car and holds onto Soos. Soos slides up to the top of the track. And after a few seconds, Soos descends downward while Dipper and Mabel screams at the top of their lungs. Soos flies off the track and lands directly near his house. Dipper pulls himself together and sends Soos back to his house. Soos steps on a pebble.]
Soos: Ow Dude! [strains]
Dipper: Oh, brother. [falls asleep as he is completely tired from having such an eventful night]
Soos: [notices Dipper is now sleepwalking] Oh! Hey Mabel do you need to help your brother with his sleepwalking! [Mabel notices Dipper is now sleepwalking] [Dipper sleep-walks into the street.]
Mabel: Oh, he'll be fine come on Soos let go inside and tell you what happened when you sleepwalking. [Soos and Mabel goes inside his house and goes back to sleep. As Soos closes his door, crashing noises are heard as Dipper is getting run over by the cars, ending the story.]
