"Rock-a-Bye Bivalve" is a SpongeBob SquarePants episode from season three. In this episode, SpongeBob and Patrick care for a baby scallop.



Rock-a-Bye Bivalve 015

SpongeBob and Patrick find a baby scallop.

SpongeBob goes to the mail and takes out the rubber band from the newspaper to play with it. While he's playing, SpongeBob hits Patrick, who is also playing with a rubber band. They then say bye to each other, until they hear chirping and both say they didn't make the noise. They spot a baby scallop in a coral tree who was making the noise.

They name him "Junior" and decide to adopt him, with SpongeBob as the mom and Patrick as the dad. Upon taking him inside his house, SpongeBob decides to use his pants as a cradle for Junior. Patrick takes a look at him in the pants and Junior starts nibbling on Patrick's head, implying hunger. The pair offers him various foods, such as a Krabby Patty, a tiny Krabby Patty, french fries, a donut, and lastly, an apple. A worm pops out of said apple and starts speaking. Junior is interested in the worm, as SpongeBob sees he wants to eat it, so he feeds him it, terrifying the worm and leading the worm to be swallowed by Junior.

After Junior's hunger is satisfied, he suddenly starts crying. SpongeBob tries to cheer him up with a puppet but it doesn’t work until Patrick finds out that he needs a new diaper (Patrick knows this well because he apparently wears diapers himself), so he gives him one, which calms down Junior's crying.

SpongeBob and Patrick, walking out of the house and taking Junior for a stroll.

Afterwards, a montage of SpongeBob and Patrick going out dressed as parents, taking Junior on various adventures, is shown. They then return home at night and put Junior to sleep in a cradle in SpongeBob's bedroom, soon going to sleep themselves.

The next morning, Patrick eats breakfast and then explains that he has to go to work since he is the father, thus leaving SpongeBob to do all the housework. He promises to give SpongeBob a break when he gets home. Eventually, he returns home only to be exhausted from work, and then decides to sit on the chair and watch TV for the rest of the night. This goes on for several days until SpongeBob can't take it anymore.

SpongeBob angrily lashes out at Patrick. He then shows all the diapers that Junior used. Patrick then realizes the error of his ways and promises to come home at 6:00 and give SpongeBob the whole night off. However, he returns at 12:00 AM from a party at work. SpongeBob isn't happy and confronts him on his broken promise as the latter gets annoyed with his constant nagging. SpongeBob follows Patrick, who said that he was going back to work, only to find out that "work" consists of Patrick watching television under his rock. SpongeBob confronts him on this, as Patrick explains that it isn't as easy at it seems; sometimes he has to move the antenna, sometimes he loses the remote, and sometimes he has a very itchy butt. SpongeBob doesn't excuse him, though tells him he forgot his briefcase and then opens up Patrick's briefcase and dumps ice cream and donuts all over Patrick.

"Oh, so this is the thanks I get for working overtime?"

An irritated Patrick then reveals that he wasn't home by 6:00, as he decided to "work" overtime. Infuriated, SpongeBob yells "Overtime?" and then the two begin to fight until they see Junior jumping out a two-story window. They immediately try to catch him, but fail and begin crying for him, believing him to be dead and proclaiming themselves "bad parents."

Rock-a-Bye Bivalve 113

Junior about to leave his adoptive parents.

However, they realize that Junior is alive and well, and has learned to fly. After Junior kisses SpongeBob and flies away, Patrick demands a kiss from Junior. The latter drops a coconut on the former's head to get back at him for his laziness, but still gives him a kiss, and Patrick responds "That's my boy." After the parents say goodbye to their son, they were proud they look after him. Patrick says "Let's have another" and SpongeBob makes a shocked face as the episode ends.

  • "Rock-a-Bye Bivalve" was ranked #89 during the Best Day Ever event on November 9–10, 2006.
  • Due to SpongeBob and Patrick's "relationship" in this episode many people insisted that this episode is promoting gay marriage.[4]



  • This episode premiered in Canada on October 18, 2002.
  • This episode takes place before "Valentine's Day," "I'm with Stupid," "Patrick SmartPants," "That's No Lady," "Welcome to the Bikini Bottom Triangle," "Krabby Road," and "The Battle of Bikini Bottom" because in this episode, SpongeBob mentions that Patrick has never worn a shirt, but in the aforementioned episodes, he is seen wearing a shirt.
  • This is the third time SpongeBob lets a wild animal stay at his house. The previous times were in "Jellyfish Jam," and "My Pretty Seahorse."
  • When SpongeBob is wearing hair rollers on his head, he has orange hair.
  • Normally in the show, worms are parodied as dogs, while snails are parodied as cats. Yet in this episode the worm was really a real worm. This is possibly because it is from the land, not the sea.
  • This episode has the most time cards with a total of five time cards.
  • For some reason, when SpongeBob and Patrick are trying to save Junior from falling out the window, SpongeBob tells him to jump into his pocket. Considering the current situation he and Patrick are in, it's possible he is saying it out of panic.
  • When SpongeBob shows funny faces, you can see the side of his head before he reveals he is using a puppet.
  • The word "bivalve" is another name for a mollusk, an oyster, or a clam.
  • When Patrick realizes what's wrong, the puppet appears to be living just like SpongeBob as he made a regular face. This could be related to SpongeBob's budding as seen in "Pressure."
  • Patrick reveals he has worn diapers for almost a year after changing Junior for the first time, but in most of his other appearances he is shown wearing briefs. Another time he was seen wearing diapers was in "Money Talks."
  • In certain countries, Patrick's line "Let's have another." along with SpongeBob's shocked reaction to the quote were cut out. This is most likely because the line contains sexual references.
  • SpongeBob stores used diapers in the refrigerator, the couch, and the walls. While these are all weird places to put diapers, the refrigerator is the worst, as it's never a good idea to put used diapers anywhere near food, unless SpongeBob cleared out the fridge.
  • Instead of letting Patrick go to his "job" everyday, SpongeBob could have just made him stay home with Junior while he went to his own job at the Krusty Krab, or brought Junior with him to work. But this episode might possibly take place sometime before SpongeBob got his job at the Krusty Krab, or he could just be on vacation.

  • Patrick's large breakfast appears to have the following:
    • Kelpo cereal
    • Some cereal with rounded torus shapes for the cereal, with milk
    • Eggs with bacon and hash-browns on the side
    • Butter on toast
    • Coffee in a mug that shows the words "Dad's Mug"
    • Orange juice
    • Pancakes with butter
    • Blueberry muffins
    • A container full of sausages
  • The time card "12:00 Midnight" is similar to the title card of "The Algae's Always Greener."
  • In the Croatian dub, the episode's name is "Spavaj mi Spavaj Školjkice," which translates to "Sleep You Sleep Bivalve."
  • The time cards in the episode are said after the last word SpongeBob and Patrick said except for "12:00 Midnight" in which the last word said was 6:00.
  • The "Uhhh..." time card uses the same background as the title card for "SpongeGuard on Duty," except without the lifeguard rescue tube.

Cultural references

  • When the worm says "We will bury you!", it is a reference to a famous speech by a Russian leader, Nikita Kruschev, in which he took off his shoe and slammed it on the podium saying in Russian "America, we will bury you."[5]
  • The title is a pun on the traditional lullaby "Rock-a-Bye Baby" since the title is referring to the baby clam.
  • The Serbian title, "Uspavanka za Ljuskara M.", is a pun on the title of the album, "Uspavanka za Radmilu M.", by ex-Yugoslav rock band Bijelo Dugme.


  • When SpongeBob and Patrick are trying to grab Junior before he falls to the ground, there are various closed captioning errors.
  • Junior's mouth stops moving when he's crying and it doesn't match the lip sync on his mouth.
  • When SpongeBob and Patrick are trying to catch Junior, SpongeBob says, "Come to daddy," but SpongeBob was the "mommy." Considering the current situation he and Patrick are in, it's possible he is saying it out of panic.

    M&E Error in "Rock-A-Bye Bivalve" (German Dub)

  • In the scene after the tomorrow time card, SpongeBob is shown with a black tie, and changes back to red in the next scene; this also happened in "Plankton!" and "SB-129."
  • When Junior was in SpongeBob's pants, SpongeBob was in his underwear. When he goes to feed him, SpongeBob's pants are back on.
  • Unless the motor on Gary's skateboard was connected to the wheels on the underside, then it shouldn't have been able to move.
