He has a rusty spatula for a left hand and has dark red eyes and a black hunch-backed body.
Squidward creates the character of the "hash-slinging slasher" in order to scare SpongeBob as a form of entertainment during their 24-hour night shift.
According to Squidward's story, the hash-slinging slasher was a former fry cook who worked at the Krusty Krab before SpongeBob and was more clumsier than him. One night, the slasher accidentally severed one of his hands by mistake while cutting Krabby Patty meat. He replaced his hand with a rusty spatula.
Later, when he was going home, he was fatally run over by a bus and "fired" at his funeral. Out of vengeance, his ghost returns to the restaurant every Tuesday night via the bus that killed him and "gets" unsuspecting victims. However, his presence is announced by (in sequential order) flickering lights, a phone call with nobody on the sending line, and the arrival of the bus that killed him, stopping just outside the Krusty Krab.
Squidward later confesses that he fabricated the story in response to SpongeBob's almost-frenetic-and-melodramatic screams of terror. Later that night, however, it seemed that the events of his story were coming true. Eventually, it is revealed that the hash-slinging slasher, or what they thought was him, actually came to apply for a job at the Krusty Krab. He was also revealed to be the cause of the latter two "signs" signalling the hash-slinging slasher's arrival, with Nosferatu switching the lights on and off.
He had the same role as the episode.
He was mentioned in this book.
He is seen in the "Graveyard Shift" segment of the book, where he has the same role he has in the episode.
He is seen in the Rock Bottom level.
The hash-slinging slasher appears in Squidward's stage (B-Movie) which was a prank by SpongeBob and Patrick to scare Squidward. If the player loses all of their lives, SpongeBob and Patrick reveal themselves and scare Squidward, but if the player wins, SpongeBob and Patrick fall, with Squidward looking in annoyance.
He appears on the comic's cover as part of the angry crowd of villains staring at SpongeBob.
