In the kitchen of the Krusty Krab, Plankton hides in one of the sesame seeds of a bun, attempting once again to steal the secret formula. SpongeBob takes the bun Plankton was hiding in, and made a Krabby Patty with it, which he delivers to Sandy. Sandy partly unzips her suit and slips the patty into it. Plankton jumps out of the sesame seed just before Sandy takes a bite. Then he faints because 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 literally rips off her fur pelt and bikini. Sandy is almost completely bald and pink, and is wearing a bra and panties in a shower. She picks up her fur coat, sniffs it, and hangs it on a hook. She resumes her shower, even though she is still wearing her bra and panties. 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 "I can breathe underwater now, simple as that." 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 sets the formula down on a table. Plankton cheers happily in Sandy's pelt, because 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. 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. 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. Meanwhile, at the Krusty Krab, SpongeBob is giving Plankton an irritating lesson where he has to put the bun on the exact spot, but he's always off by a random amount like "3.6 millimeters". 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 they will take the "sicko" away, Sandy thinks that they are trying to arrest Plankton for stealing a Krabby Patty Secret Formula, but the police arrest Sandy for public nudity instead. At the end, Sandy sighs.
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.
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 didn't 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 w/ her pelt but stayed on. Her bikini top also had shoulder straps when she ripped it off.
Throughout the episode, Sandy's bra changed. Sometimes its two cups were joined directly together, sometimes there was a small bridge between them (thus giving Sandy more cleavage).
When Sandy took a shower she did not remove her bra and her panties. Likely because this is a kids show. Usually if a female character in a non-satire show is taking a shower the camera will either only show her head and neck.
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 a 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's in pink.
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 w/ The Inside Job.
This is the first time a bra (discluding bikini tops) is shown in SpongeBob.
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.
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 of course, means completely serious.
In one scene at the park, Sandy's eyelashes disappear.
When Sandy realizes her fur is gone, she guessed that she left it outside. However, she did put it in the bathroom.
There are more than one Karen in one scene. Although, it may be possible to transfer her data to another computer.
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.
When Sandy pulls the Krabby Patty into her suit through the arm, and then proceeds to eat it, it is physically impossible because the Krabby Patty is on the outside, while her hand is on the inside. The patty would have no way of actually getting into the suit.
When Sandy lifted her Krabby Patty it should have appeared wet possibly dripping with water but it appeared physically fine not even looking bended.
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.
