Squidward and SpongeBob teleport to him, and they catch him in the act. They look around for a bit, but they eventually find him. Squidward gets out binoculars, and they start looking for the Hash-Slinging Slasher. Squidward believes it to be the Hash-Slinging Slasher, and they have a conversation about it, and decide to investigate.
They have a conversation about the noise, but Squidward says he's never heard the noise, until it happens again and he hears it. He asks the man to pull the newspaper from over his face, and it reveals to be Squidward. He pulls up to a spot where he sees a man holding a newspaper, he thinks he has his guy, so he goes over to the man. SpongeBob continues driving towards where the radio transmitter says the noise is, and states that he is 13 minutes away from where the noise is coming from. He then gets in his car and drives toward the noise. Then SpongeBob picks up his radio transmitter, and says the sound is only 15 minutes away. They start having a conversation on what could be making the noise. SpongeBob comes out of the car, angered, and starts yelling at Mrs. Puff then comes out of her house with a pellet gun, and shoots SpongeBob's car window, and it cracks. The next scene starts with SpongeBob driving down a road, looking for the thing making the noises. After that, a shot of Patrick being sad while going back inside his house is shown. SpongeBob nicely declines his offer, and drives away. Him and SpongeBob have a small conversation about the knocking sounds, and Patrick eventually asks SpongeBob if he can join him on his journey to find out about the knocking sounds. He drives by Patrick's house, and Patrick leaves his house, wondering as well what the knocking sounds were. He gets a police car out, and the words "PoliceBob OfficerPants" are shown on screen, and he drives away to figure out what that knocking noise that woke him up was. He decides to become "PoliceBob OfficerPants" to investigate further into the noise. SpongeBobs repeated scared yelling prompts Squidward to tell him that the story is fictional. He goes outside to investigate, but finds nothing. Squidward soon gets bored, and tells SpongeBob about the 'hash-slinging slasher' just to scare him. An odd knocking sound happens, but SpongeBob remains asleep, it happens again, but this time he wakes up.
The episode starts out with a time card saying, "12:00 A.M." A show of SpongeBob's house follows, and it zooms into SpongeBob sleeping in his chair.
