Who was the Episode MVP ?

  • Doing Time was way better

    Mermaidman and BarnacleBoy IV was kinda boring to me. Doing Time was actually pretty interesting and funny.

    MMBBIV- 6/10

    Doing TIme- 10/10
  • I liked these episodes

    I liked these episodes just as much as Hooky, Mermaid Man and Barnacle Boy II, MuscleBob BuffPants, and Squidward, the Unfriendly Ghost (these all aired today).
  • Man, I thought I was the ONLY one who hated MM&BBIV

    MM & BB IV

    Three words: very, weak, story.


    Doing Time

    Better than it's first pairing



  • One of the weakest pairs

    MM and BB IV: This is just a mediocre episode of SpongeBob. Not only that, but it's the weakest Mermaid Man and Barnacle Boy episode I've ever seen (my second weakest would be season 5's Mermaid Man vs SpongeBob). I'll just get to funny parts and then the parts on why I didn't like this one very much. I laughed pretty much most of the first few minutes (Barnacle and Squidward fighting about their noses, SpongeBob trying to get autograph, SpongeBob messing with the shrink ray before it's got out of hand). After that, it's sucked and I didn't like Squidward threatening to tell Mermaid Man. The next 6 minutes was a waste of time as well when SpongeBob got all shrunk. I didn't like everyone cutting off SpongeBob's body because of that. But I did like that he turns everything back to normal expect Plankton is larger (funniest part of the episode). Overall, a mediocre episode for MM and BB standards. 5/10

    Doing Time: This was better than the first pair but it's still got the problems. A few parts are boring and it was never my favorite storyline. There were funny parts like SpongeBob destroying everything at Bikini Bottom (although I'm surprised the episode already started with that), the fruit punch coming out of the retirement home, everything that SpongeBob and Patrick did to get Mrs. Puff back (funniest was SpongeBob as the robber), and a few more. Overall, a great episode and way better MM and BB IV. 8/10moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (33)

    • Since no one returned to normal size by the end of this episode, everyone is small in every episode after this one.

    • When Patrick is changing the "M" on Mermaid Man's belt to "W," SpongeBob's face holes disappear.

    • When SpongeBob was running towards Patrick on the looks for advice on "Mermaid Man and Barnacle Boy IV," he's wearing his regular pants instead of Mermaid Man's belt.

    • When SpongeBob is speeding past the patrol officers, they choose to chase him for he had no front license plate, instead of because he was speeding.

    • Shouldn't SpongeBob have died when one of the citizens of Bikini Bottom cut off one of his organs?

    • When the citizens of Bikini Bottom attack SpongeBob in "Mermaid Man and Barnacle Boy IV," he had a backbone, but SpongeBob is an invertebrate as admitted in "Squirrel Jokes."

    • When Patrick held Squidward, he appeared to be thinner than usual.

    • When SpongeBob shrunk the city, it seemed a lot smaller than usual.

    • If everyone shrunk to the size of pickles, then how could Plankton be taller than the tallest buildings?

    • The size of the citizens changed throughout the episode. First, they were the size of the pickles, then they were the size of Plankton, and then everyone was the size of dust.

    • When SpongeBob shrunk Squidward, his cap was on, but in the next scene, it was gone.

    • Sponges don't have internal organs.

    • Mermaid Man's belt is purple in the episode. In other episodes, it's yellow and black.

    • When Plankton returns from vacation at the end, the bus Plankton got off of was the only road you could see in that scene. When SpongeBob shrunk the town, you can see no roads in the town.

    • In "Doing Time", when the guard throws Mrs. Puff in the yellow room, there's a rubber ducky. When Spongebob starts laughing, you can see that the ducky disappears.

    • Look Hard: In the scene where Patrick tells SpongeBob the way to return Squidward to normal, Patrick said to switch the M to W. But when SpongeBob activated the ray, the W was back to an M. Which probably explains why the town did not return to normal.

    • Scooter appears in this episode, even though he died in "Bubble Buddy".

    • Spongebob can't get the citizens of Bikini Bottom to grow back to normal, but in "Mermaid Man and Barnacle Boy I" Spongebob mentions a ray that made stuff grow 6 times there size. Why couldn't Mermaid Man (or Barnacle Boy) use this to make everyone grow back to normal?

    • Response to the parking meter goof: It's not a goof. I also have quoted proof, too:

      Cop: This'll fix ya!
      (When they're finished fixing that parking meter...)
      Cop: Now let's get that one!

      They were actually FIXING the parking meters, not wrecking them.

    • Reply to the Unfinished Bridge goof: Comedy, people. Comedy.

    • Response to the first one: Mermaid Man is an idiot, so he wouldn't know that setting it to wumbo wouldn't work!

    • How could Mrs. Puff have fallen asleep in the car if she was screaming like mad? And how could she have had a fantasy if she was screaming like mad as well?

    • In Doing Time when Mrs. Puff was first put in jail she had only one bed in her cell but later on she has two.

    • In Doing Time at the end when she was in the car with Donna, at first when you see a wider view of the car there was only Mrs. Puff in the car.

    • In MM+BB 4 if you see the boat mobile when they hit the car alarm it looks like a 1959 Caddilac Elderado but in MM+BB 1 and 3 it looks like a regular boat.

    • In the episode Doing Time, when Mrs. Puff says "Yeah, it must be the heat." her hat turns blue for a second.

    • At the end of "MM & BB IV" where is MM's belt?

    • NO, he told him to turn it to wombo, but he never did because 1 second later it is set to M (for mini)

    • Doesn't Donna want her chili when Mrs. Puff is on Kitchen Duty?

    • In "Doing Time" when Mrs. Puff drinking the water her hat turns black instead of the normal red.

    • Spongebob and Patrick were smaller than normal when they were in the Chili barrel.

    • Do you notice how when spongebob first starts to shrink the people, they're about the says of a baby doll, but then the whole town is small enough to fit in a jar, and then they get even smaller because Plankton is about the size of the size they were when they were in the jar and he is bigger than the town?

    • In doing time, when Mrs. Puff and Spongebob fell onto the truck the second time, the other boats fell and their boat wasn't there anymore.

  • QUOTES (35)

    • Patrick: Ah ha! Here's the problem.
      SpongeBob: What is it?
      Patrick: You got it set to "M" for "Mini", when it should be set to "W" for "Wumbo".
      SpongeBob: Patrick, I don't think "Wumbo" is a real word
      Patrick: Come on, you know. I wumbo, you wumbo, he she me wumbo. Wumboing......
      Squidward: I wonder if this high is high enough to kill me?
      Patrick: ....Wumbology? The study of Wumbo? It's first grade, SpongeBob.
      SpongeBob: Patrick, I'm sorry I didn't trust you before.
      Patrick: Okay, fire away! (pushes button) IT WORKED!!

      Mrs. Puff: No, why'd you bring him?

      Mrs. Puff: Oh, hi, Donna. It's chili, same as always.

    • SpongeBob: Mermaid Man's Secret Utility Belt! The emblem of submerciful justice! For 65 years this belt has helped prevent the fall of nations . . . and pants.

      Squidward: What have you got there?
      Spongebob: Nothing.
      Squidward: No really.
      Spongebob: Nothing.
      Squidward: You've got something there let me see it. (turns Spongebob around and picks him up by the belt)
      Spongebob: No, no, no!
      Squidward: (gasps) Is that Mermaid Man's belt?
      Spongebob: Yes.
      Squidward: Wow! I can't believe he lent it to you.
      Spongebob: Me...uh...either.
      Squidward: (gasps) He didn't lend it to you, did he?!
      Spongebob: Please don't tell.
      Squidward: You stole it!
      Spongebob: Please don't tell!
      Squidward: Oh, I'm telling.
      Spongebob: Squidward if Mermaid Man find out, he'll kick me out of his fan club for sure. Please don't tell!
      Squidward: Uh-oh. There's the phone.
      Spongebob: No.
      Squidward: I walking towards the phone
      Spongebob: Don't.
      Squidward: I'm getting closer to the phone.
      Spongebob: Do-ho-ho-ho-ho-hont.
      Squidward: And now, for the moment we've all been waiting for... (has receiver in his tentacle)
      Spongebob: I'M BEGGING YOOOUUUUU! (starts to rip himself in half)
      Squidward: Hello. I'd like to speak to Mermai.... (A flash of green light covers Squidward. A second later we see Squidward shrunk)

    • Ms. Puff: You can't fool me! Your Spongebob and the guy who likes the chili!

    • Mermaid Man: The thing is you have to own up to your mistakes and...
      Mermaid Man: Umm... yes, let's see... did you set it to wumbo?

    • Squidward: Wonder if a fall from this height will kill me...

    • Patrick: Its not all that bad, He'll find love one day...
      SpongeBob: Yeah...
      Patrick: Like this pickle... see they like each other already. (starts smooching the pickle in Squidward's face like they were kissing)

    • Bikini Bottom Citizens: GET SPONGEBOB!

      Other Officer: Yeah. That guy had no front license plate. LET'S GET HIM!

      SpongeBob: Patrick, wait!
      Patrick: Fighter pilot! (makes noises)And here comes the giant fist!
      Squidward: Ahhhhh!
      SpongeBob: Patrick, wait! That's not an action figure. That's really Squidward. I shrunk him by accident.
      Patrick: Oh. And here comes the giant fist!
      Squidward: Ahhhhh!

      Mermaid Man: Oh, yeah.

  • NOTES (14)


    • "What's up, Sponge?"
      When SpongeBob is running zapping everyone in Bikini Bottom on "Mermaid Man and Barnacle Boy IV" someone says "What's up, Sponge?" this is a reference to Bugs Bunny's catch phrase "What's up, Doc?"

    • Donna: So what's for dinner, Puff Mama?
      Donna is making a reference to the famous rapper, Puff Daddy.

    • Mermaid Man: And a Silly Meal for the lad.
      A Silly Meal is a reference to the McDonald's "Happy Meal" with the toy.
