"Terror Tales of the Park IV" is the fourth episode in Season 6 (and the one-hundred and fifty-seventh episode overall) of Regular Show. It first aired on October 29, 2014.


The park guys try to keep Muscle Man awake with scary stories on a long drive so that they can meet his mom.



Muscle Man tries to scare off two children who come to the house trick or treating but fails to do so with his mask on but as soon as he removes his mask, the children get scared and run away screaming. Muscle Man then enters the house and tells the park workers that there will be no more trick or treaters. Benson then asks fellow park workers what they want to do. Muscle Man suggests telling scary stories. Mordecai says that they do that every year and then Rigby suggests that they should do something really scary. After a couple guesses (Skips: Rent a few genre films, Pops: Go to bed early), he suggests going to haunted house, commenting, "Those are the scariest" to which Muscle Man replies, "You know who else is the scariest? MY MOM." Everyone is annoyed with Muscle Man making another "My Mom" joke, but they soon realize that none of them (not even Hi Five Ghost) have even met her. So, they finish the rest of their Halloween night traveling all the way to Mrs. Sorrenstein's home to meet her, though they're forced to tell scary stories while they go there or Muscle Man won't introduce them to her. As Muscle Man drives the crew, Pops volunteers to tell the first story...

Pops tells a story about being sacrificed to a mysterious hole in the park. After the ending, Muscle Man is not satisfied with the result and threatens to turn the car around. Not willing to accept that, Benson begins to tell a scary story he had come up with...

Benson tells a story about Mordecai and Rigby dying and coming back to haunt him, with a twist ending that Benson was the real ghost all along. By the end, the Park workers aren't too thrilled with the ending as it was too expected. Soon, they eventually arrive at a trailer park where Muscle Man's mother lives. They then head to the top of the hill, where her trailer's supposed to be. As they are all hiking their way up, Muscle Man annoys everyone (except Fives) with yet another "My Mom" joke. Rigby decides to help pass the time by telling the third and final scary story...

After Rigby's story, Muscle Man says that he never knew that Rigby was a master of Ball lightning. After the stories are told, they finally see the trailer that Muscle Man's mother lives. Rigby just wants to see his mother and leave. Muscle Man tells him that he has to tell her that she has company because she doesn't like surprise guests. Pops thinks that Muscle Man's mom that the foam tombstones are nice, but Muscle Man tells him that those aren't foam and that they are real, much to the dismay of Pops. Muscle Man tells them that she's ready to see them. Ms. Sorenstein shows up in a hockey mask, scaring them. Mordecai tells Muscle Man that this is a prank, thinking that he was in the mask until the real Muscle Man comes out. Muscle Man laughs in delight, telling them that the trailer was not where his mom lives. He then says that this was all planned out and that Muscle Bro was here the whole time until he comes out, scaring them, including Muscle Man. The person in the hockey mask tells them "You know who else like scaring people?" and then taking off the hockey mask to reveal that it was indeed Muscle Man's Mom and not John Sorrenstein, scaring everyone, They then run out in horror. Muscle Man's mom comes out, creating a large gap in the trailer. She then tells them that they forgot their candy. She then breaks the fourth wall, telling the audience "Happy Halloween!" and eats the candy. She unzips the costume and tells the audience that it gets Muscle Man and Muscle Bro every year.
