In the beginning of the episode, SpongeBob receives a "ransom" note from his cousin BlackJack, saying that he has been released from prison, has paid SpongeBob's parents a "visit," and has challenged him to a wrestling match for their safety. When he arrives at their house, it is wrapped with police tape, and all of the furniture is covered in plastic, which leads SpongeBob to believe a crime was committed at his parents' house. He finds another note from BlackJack, this time saying he's going to pay SpongeBob's Grandma a visit. SpongeBob arrives at Grandma SquarePants' house, and she says BlackJack recently called her, and left a message for SpongeBob, saying he has some "loose ends to tie up." This results in SpongeBob thinking BlackJack tied up his parents.
SpongeBob seeks help from his uncle, Captain Blue SquarePants, a retired police captain. But because of listening to various loud sounds, instead of helping SpongeBob save his parents from BlackJack, he makes SpongeBob partake in manual labor, including lawn mowing, building a fence, trimming a coral tree, and much more. When SpongeBob finishes, SpongeBob stops the music and tells the situation. Captain Blue refuses to help, saying that if he was in Spongebob's place, he will just go home and tells him that he's not cut out this type of work but he does drive him to BlackJack's house, which is ironically (and literally) right next door. SpongeBob stands in front of BlackJack's front door for a moment regretting his decision (and remembering what his uncle said), when he hears mother scream from inside the house. SpongeBob instantly runs into BlackJack's house, and into the basement. SpongeBob goes in to confront his foe and save his parents, but it is revealed that his parents were never in any danger, and that they are holding a party for BlackJack to celebrate his release.
They explain to SpongeBob that BlackJack has renounced his "criminal" ways of littering, and that their house was closed off due to a krill infestation. BlackJack then enters the room, still intent on beating up SpongeBob, but SpongeBob is now prepared to stand up for himself. As BlackJack charges at SpongeBob, it is revealed that BlackJack is no bigger than SpongeBob's foot, and that he cannot do any harm whatsoever, as the episode ends.

- This episode was originally going to be titled "In Search of Ma and Pa Sponge."
- Since mid-2009, the Nickelodeon USA broadcast of this episode uses the soundtrack "Secret Agent 00 SquarePants" as the title card cue instead of "K-55," possibly due to copyright issues. This is also true for all Nicktoons USA and Nick@Nite broadcasts, as well as all streaming releases on Amazon Prime Video, Paramount+ and iTunes. The current DVD releases still use "K-55," however.
- The return address on the envelope that has been covered by saliva can be made out as "BlackJack, 133 Coral Rd or Bd, Bikini Bottom."

- When SpongeBob has a flashback to when he was a kid, he is shown wearing a bow tie.
- The bowl on Grandma's counter is the same as the one in "Grandma's Kisses" but with a different, clearer shape.
- After SpongeBob says, "Cleaning up the mess?," his face deflates just like Squidward's face does at the end of "Squid's Day Off."
- 346 minutes equals 5 hours and 46 minutes which means that SpongeBob spent almost six hours mowing the lawn at Uncle Captain Blue's house.
- The door knocker on BlackJack's house has a hand attached to it with a bone sticking out. This resembles SpongeBob's hand.

- This episode features more appearances of SpongeBob's relatives than any other episodes, with a total of five characters.
- This is the second appearance of SpongeBob's grandmother, who first appears in "Grandma's Kisses."
- This means that she took six years to return as a character.
- This is the third episode to have a title card that only has light around the text. The first and second were "Squirrel Jokes" and "Funny Pants," respectively.
- This is the fourth time SpongeBob got split himself in half just like on "Texas," "Procrastination," and "I Had an Accident."
- Like most of episodes in season 5 and first half of season 6, in the Bahasa Indonesia dub, the scene where SpongeBob entering his parents' house was skipped to the daydream scene due to the time constraints.
- BlackJack is a reference to the gambling card game of the same name.

- When SpongeBob is at his parents' house, there is an image above the couch, that shows a sun on some rocks in goo. In SpongeBob's idea of what happened, the image shows dark rocks, like it is night.

- In SpongeBob's idea of what happened to his parents, the stripe on Harold's hat is lighter than normal.

- When SpongeBob builds the fence, he builds it all around Captain Blue SquarePants' house, but when he drives SpongeBob to BlackJack's house, the fence has an opening.
