"Chimps Ahoy" is a SpongeBob SquarePants episode from season 4. In this episode, Sandy's bosses visit to see her inventions, but if they don't like anything, she must leave Bikini Bottom.



As the episode starts, the Chimpanzee beneficiaries of Sandy's undersea treedome are paying a visit to see what progress she has made with her inventions, but Sandy doesn't think any of her work will satisfy the chimps, and if they don't like what she's invented, Sandy could lose her funding, forcing her to leave Bikini Bottom. SpongeBob and Patrick decide to help their distraught friend by taking over her work and finishing her inventions for her.

Sandy's bosses.

At first, Patrick has ideas of things that have already been invented, such as a pencil and a mirror, which ironically is actually a parallel universe. After hours of hard work, SpongeBob and Patrick invent a back-scratching, hair-combing, nose-picking ukulele-tuner.

When the chimps arrive, Lord Reginald is the first to test it. Shockingly, the invention works, but has kinks as it feeds him pudding and when tuning the ukulele, the machine malfunctions, hits Reginald with the ukulele, slaps him, then starts attacking him with all sorts of weapons.

This is where our research money went?

Meanwhile, Sandy hears the screaming of Reginald and arrives just as the machine spits out Reginald. The chimps decide to close down the treedome, but when Dr. Marmalade holds out a banana, Sandy's "nutcracker" peels it for him. It is revealed that this is an invention that Chimps have been searching hundreds of years for. They chatter excitedly and decide to let Sandy stay for 20 more years, including a higher salary.

After the chimps leave, the episode finishes with Patrick deciding to test out the machine that injured Reginald, which of course, malfunctions on him, yet he still yells out "Alright!"

Running gags

  • Patrick wants people to call him "Mr. Dr. Prof. Patrick."

  • The back scratcher that SpongeBob buys at the beginning of the episode costs him 52 box tops.
  • This is the first episode to have aired on the Nick Friday Night event.
  • This is the first episode to have actual land mammals in it besides Sandy, Mermaid Man, and Barnacle Boy.
  • This is the first episode to reference the Goofy Goober franchise outside of the first movie.
  • This episode is the second time that Sandy sings a song that upsets SpongeBob and Patrick to the point of crying. The first time is in "Texas."
  • Based on the comparative size of SpongeBob and Patrick when compared to the humans depicted in The SpongeBob SquarePants Movie, the chimps depicted in this episode would only be 2-3 inches tall.
  • Although Squidward doesn't appear in this episode, he only speaks, only having one line.
  • The chimps have been searching for the banana-peeling nutcracker for 117 years.
  • This is the only episode to feature the track, "Hall of Fame [#9]."
  • The things holding SpongeBob's invention together:
    • Bandages
    • Screws driven into bottle caps
    • Pieces of tape made into an X
    • A taped-down lollipop
    • Chewed-up bubble gum
  • The towns for those that have nowhere else to go, as mentioned by the bus driver, in which the bus makes stops to:
    • Quittersville
    • Failuretown
    • Loserburg
  • SpongeBob's invention is called the "Automatic Back Scratcher, Hair Comber, Nose Picker, and Ukulele Tuner 9000."
  • The peanut SpongeBob talks to says, "It's dark in here."
  • The inventions Patrick thinks of:
    • Pencil: a stick that can be used to draw or write stuff with
    • Light bulb: a glass ball that lights up so the user can see in the dark
    • Mirror: a parallel universe
  • In this episode, SpongeBob and Patrick's water helmets are worn with the openings facing up, the same as how they are shown in the episode "Tea at the Treedome." Normally, they face down.
  • The list of items shown when "The Automatic Back-Scratcher, Hair-Comber, Nose-Picker, and Ukulele-Tuner 9000" goes haywire include:
    • An electric saw with a circular blade
    • A flamethrower
    • A pair of scissors
    • A corkscrew
    • An aerial poison dart
    • A taser
  • Inventions the chimps have been searching for many years:
    • Banana peeler
    • Poop thrower
  • The chimps exclaimed they searched 117 years for a banana peeler, so they could be older than that, making them the oldest mammals in the show. Of course, they could simply be referring to them as a species, or the company they work for.
  • When Sandy sings the "birds that fly upon the ground" line, a manta ray swims by, releasing a bird call. This is strange because most birds are depicted as scallops.
  • In Sandy's song, string squeaks can be heard camouflaged in the background of her music. Although in "Texas," one can hear that the guitar strumming sounds distorted, so the string squeaks cannot be heard.
  • SpongeBob's reflection has a Russian accent.

  • Right near the end of the episode, if you listen closely as the chimps leave and say "Goodbye!," one of them is heard singing the line.
  • Nigel Planer, Christopher Ryan, and Rik Mayall all played on the British sitcom The Young Ones and are all in the UK comedy group The Comic Strip.
  • In the beginning of the episode, Sandy says that the chimps are coming that afternoon. When SpongeBob and Patrick want to help, they work all night, and the chimps come the next day. It's possible that there has been a change of schedule.
