In the kitchen of the Krusty Krab, Plankton hides in one of the sesame seeds of a bun, attempting once again to steal the Krabby Patty secret formula. SpongeBob takes the bun Plankton is hiding in and makes a Krabby Patty with it, which he delivers to Sandy, who is at the Krusty Krab. Sandy partly unzips her suit and slips the patty into it. Then, Plankton jumps out of the sesame seed just before Sandy takes a bite. He faints shortly after since there is no water in Sandy's suit.
Later, Sandy returns to the Treedome. She goes into her bathroom, where she takes off her spacesuit and glass helmet (with unconscious Plankton inside). Then, she gets in the shower, turns it on, and rips off her fur pelt and bikini. Sandy is almost completely bald and pink and is wearing a bra and panties in the shower. She picks up her fur coat, sniffs it, and hangs it on a hook. She resumes her shower after she does this.
Drops of water from the shower fall in her helmet, thereby reviving Plankton. Then, Plankton notices Sandy's pelt, hanging on the hook. He takes the pelt, locks Sandy in her bathroom, and brings Sandy's pelt to the Chum Bucket. He motorizes the pelt and moves it to the Krusty Krab pretending to be Sandy. SpongeBob is happy to see "Sandy" again, but notices that "she's" not wearing her space suit and helmet. "Sandy" replies that he can breathe underwater now. SpongeBob believes "her," of course. Plankton asks SpongeBob for Krabby Patty tips or information.
After some short tips from SpongeBob, Mr. Krabs walks in through the door at the corner of the kitchen and declares that he is leaving the formula out in plain sight by setting it down on a table. Plankton cheers happily in Sandy's pelt, since stealing the formula is now much easier.
Meanwhile, Sandy finishes her shower. She wraps a towel around her body and walks over to dry her "stinky fur coat." However, her fur is gone. Finding herself locked in, she breaks down the door of the bathroom, fully aware that someone must have stolen it. She then flings the towel off herself, puts a coffee pot on her head in place of her helmet, and runs off to find the culprit, who's possibly wanting to sell her pelt on the Bikini Bottom black market. However, the Bikini Bottomites think she is naked, and make fun of her hairless pink skin, calling her a "hairless goat," a "nudist ferret," and a "naked chipmunk." Sandy makes a makeshift skirt out of seaweed to cover her "hind end," but it overheats, gets brittle, and shatters when she warms her hairless body by a vent.
At the Krusty Krab, SpongeBob is giving Plankton an irritating lesson where he has to put the bun on the exact spot of the patty, but he is always off by a random amount. He gives up, steals the formula, and tries to escape. The real Sandy enters the Krusty Krab and stops him in the nick of time. She then rolls up her fur pelt and puts Plankton in a jar of mustard. Unfortunately, the law catches up with her. When they announce that they will take the "sicko" away, Sandy thinks that they are trying to arrest Plankton for stealing the Krabby Patty secret formula, but the police arrest Sandy for public nudity instead as the episode comes to an end.
This is the first, and so far, the only time Sandy gets arrested (though, in a deleted scene of "The Great Snail Race," she gets arrested after kicking SpongeBob in the butt).
In "Survival of the Idiots," Sandy had real fur which was ripped off by SpongeBob and Patrick. She probably bought her pelt to cover her hide until her fur grew back.
This is the second time that Sandy uses something other than her space helmet to breathe underwater. The first time being in "Pressure."
Plankton can fit inside a sesame seed in this episode, but in many instances, he is the size of an insect and has the capability of carrying Krabby Patties.
Strangely, Sandy's bathroom had the lock on the outside.
It is strange that the characters didn't notice Sandy's fur having no eyeballs.
Sandy often called her pelt her "fur" as if it was her actual fur.
Sandy had a bellybutton under her fur in this episode, but she did not in "Survival of the Idiots."
Sandy wasn't any smaller under her fur, even though it was very thick.
Sandy ripped her pelt to remove it but, seconds later, it was in one piece. Also, her bikini ripped along with her pelt but stayed on. Her bikini top also had shoulder straps when she ripped it off.
Throughout the episode, Sandy's bra changes. Sometimes two cups were joined directly together, other times there was a small bridge between them (thus giving Sandy more cleavage).
When Sandy yelled at Harold, then hid in the bushes, and looked at the town from a hill, her bra appeared smaller.
SpongeBob specifies that a Krabby Patty must be cooked at the specific temperature of 274 degrees, but in "Bummer Vacation," SpongeBob said the grill must be at exactly 298 degrees. It’s possible it was changed between episodes.
When Sandy rolled up her pelt, it had no bikini top.
Sandy was arrested for public nudity, even though she was wearing her bra and panties (which look very similar to her bikini). Also, some of the citizens are not fully dressed or do not wear clothes at all, yet they aren't arrested, criticized, or humiliated. There may be some exceptions to the laws, as fish are not expected to wear clothes anyway.
Sandy rolled up her pelt when she defeated Plankton, but it was unrolled seconds later.
The title card uses a similar background as "Dying for Pie" except it is in pink. It's also similar to the "Meanwhile At The Krusty Krab" time card in "Le Big Switch."
There was an original title card for this episode (see picture). Reruns have a new title card (see above)
Impersonating someone is a crime, so Plankton should have gone to jail as well.
It is possible that, after the episode, Sandy was pardoned and Plankton was convicted for impersonating Sandy and stealing her fur.
When Plankton was knocked out in Sandy’s helmet, he did not shrivel up and turn realistic looking like SpongeBob does when he runs out of air.
In this episode, Sandy can eat Krabby Patties, but in "Pressure," she couldn't. She may have added some kind of water version of a space airlock to the suit.
It is unknown how Sandy didn't see Plankton in her helmet while she was eating her Krabby Patty.
This episode appears almost every day in the Romanian Nickelodeon, paired with "The Inside Job."
This is the first time a bra (excluding bikini tops) is shown in SpongeBob SquarePants.
This is the first time panties other than Bikini Bottomites are shown in SpongeBob.
Running Gag: People calling Sandy a naked chipmunk and a hairless goat and a nudist ferret.
If Plankton did come from the bakery, it would be impossible for him to predict the Krusty Krab or buy the selective buns.
Plankton locks the door with a bar on the outside, but when Sandy tries to get out, she is pulling the handle, what means that there would be no reason for the bar.
When Sandy returns from going underground, she pops up through a sewer cover inside the Krusty Krab. It would be very unlikely that the line would have a cover inside the main restaurant.
This episode name is a parody of the song “Someone’s in the Kitchen with Dinah.”
When Karen asks Plankton if he's serious about his plan to impersonate Sandy, he replies, "Serious as a shark attack!" This is a pun on "Serious as a heart attack," which means completely serious.
In one scene at the park, Sandy's eyelashes disappear.
In the first time Sandy's Pelt (Plankton) reaches for the formula Sandy's pelts bra strap is missing.
There are more than one Karen in one scene. Although, it may be possible to transfer her data to another computer.
While Plankton (who was in Sandy's fur) was talking to SpongeBob in the kitchen, there is one scene where SpongeBob's eyelashes disappear.
When Sandy removes her pelt, there is a short scene in which her panties have disappeared.
When Plankton impersonated Sandy, he installed a robotic endoskeleton in the pelt, but when Sandy rolls it up, the endoskeleton is suddenly gone.
When Sandy first takes off her pelt, she is wearing underwear, but when she steps out, she is not wearing underwear. When she starts taking a shower, she is wearing underwear again.
After stealing Sandy's fur, Plankton ran outside and locked the door without showing any sign of dehydration due to lack of water in Sandy's Treedome.
When Sandy left to find her fur coat, she did not take her helmet and spacesuit that were still in the treedome.
Bubbles are shown when Sandy knocks down her bathroom door after seeing that she is locked in, even though the treedome is full of air and not water.
