In the beginning of the episode, SpongeBob is at home getting ready for bed, but then he feels thirsty. He goes downstairs to get a glass of water, but then spits it out in surprise upon seeing that the entire downstairs floor is a mess. He then finds out that Patrick is sleepwalking and that he is the cause of the mess. SpongeBob then tries to wake him up by calling his name, pulling his shorts, banging on pots and pans, using an air horn, pulling on his eyelids, and using his foghorn alarm. However, all of the attempts fail and Patrick sleepwalks towards the toaster. He puts two slices of bread in the toaster, then splatters a bar of butter on it, then he eats the toaster. He burps out toast, eats it, then walks towards the refrigerator. He eats a container, then puts a carton of eggs on his butt. He then continues to walk (with his head inside the fridge) and breaks the wall. He then takes the fridge and throws it against another wall, breaking it.
He starts walking through the hole, onto a road filled with driving boats. Patrick manages to make it through, but SpongeBob gets hit by a bunch of boats, then lands on the ground on the other side of the road, later getting stepped on by Patrick.
Patrick then walks into someone's house, walks by two fish sleeping, and walks toward a bunch of glass bottles. SpongeBob quickly turns him into the other direction, then quickly picks up a pot that Patrick dropped. SpongeBob then walks into a room, seeing Patrick screaming something to some fish, but SpongeBob quickly silences him. He turns Patrick around and smacks his butt, and then Patrick walks out of the house, over to the Chum Bucket, while SpongeBob gets kicked out of the house, through the window.
SpongeBob goes to the Chum Bucket, where Patrick is about to eat some chum. SpongeBob stops him, but ends up accidentally eating the chum himself.
He then follows Patrick over to the theater, where he sees Patrick sleep-dancing on the stage. SpongeBob gets some popcorn and watches him, getting teary at the end of the performance. Patrick then leaves the stage and SpongeBob follows him to Glove World!, where he is walking on the track of the Neck Breaker. SpongeBob then gets a cart and follows him on the track. SpongeBob grabs onto Patrick, and they fly off the track, right beside Patrick's rock, to which SpongeBob leads him.
However, Patrick steps on a rock and wakes up in pain before he notices SpongeBob beginning to sleepwalk into traffic. Patrick (ironically) expresses little concern about this event and believes that SpongeBob won't be harmed. Patrick then goes back to sleep under his rock, while SpongeBob almost gets hit by multiple boats in traffic, as the episode ends.
