It was introduced in the episode "Left in the Dark", where the show presents one of the best episodes of all time, in which the Spectre Hunter is sent to the scariest place of any home: the basement. Lincoln tries to watch the episode, but first, he must beat each of his sisters to get the couch first, but when he sets the old television up for Lucy, the power goes out. After the power turns back, Lincoln beats again his sisters and gets the couch, but the episode ends immediately as he turns on the TV, much to his despair.
ARGGH! also appears in the episode "Cover Girls", where Lincoln and Clyde were watching an episode where Spectre Hunter was about to take down a ghost in a bathroom in the next episode. At the end of the episode, Lincoln was going to watch the next episode at Clyde's, but since he's dressed up as Lily (as punishment for him and his sisters dressing up as each other in order to cover for each other), he ends up getting humiliated since Clyde invited the whole class to watch an episode of ARGGH!.
In "No Such Luck", Lincoln is watching TV, and the announcer says: "Next on ARGGH!".
In "Kick the Bucket List", Lincoln and Clyde tried to binge watch it, but it was too long, so they had to fast forward it.
ARGGH!'s first major role was in "ARGGH! You for Real?", when the crew visited Royal Woods to find the Ghost of Groundskeeper Jim in Royal Woods after the group had succeeded in capturing the Ghost of Armando the Hairdresser in Erie, Pennsylvania. Lincoln and Clyde discover that the ghosts were just special effects and tricks. This has a big impact on Clyde, who disbelieves in everything. Lincoln and Hunter Spector teamed up to get Clyde back, by using even more convincing effects that Clyde thought were real. Though the flying can part turned out to be real as evidence to the fact that the Ghost of Groundskeeper Jim burped in his ghost trap. In the next episode that Lincoln and Clyde watches, Hunter Spector is in Milwaukee looking for the Ghost of Captain Jack who is said to be seen swabbing the decks of a haunted tugboat.
It also appeared on TV in "Pipe Dreams" being watched by Lincoln and Lisa as Lynn Sr. and Rita try to build their secret bathroom.
In "Friendzy", Lincoln tries to watch ARRGH! which conflicts with the other shows like Lola's show Prison Pageants, Lucy's show The Vampires of Melancholia, and the random shows of the other sisters. In one ARGGH! episode, it was mentioned that Hunter Spector was trapped in a haunted port-a-potty.
In "Ghosted!", Lincoln and Clyde dress in ARGGH! uniforms to repel the ghost that was haunting Fairway University at Lori's request. However, when it turned out that the ghost (named Shanks Bogey) brought the students good luck, Lori had the Morticians Club bring him back.
In "Haunted House Call", Lucy borrows Lincoln's ARGGH! ghost containment device to capture the specter of Buzz, warning the Morticians Club not to tell Lincoln.
