The episode begins with Squidward making a vegetable version of himself. However, he forgot the parsley, so he goes to get some from his backyard. When he tries to take it out, he ends up getting pulled underground by a bunny. Meanwhile, Squidward's meal gets burned due to sitting in the oven for too long. This makes Squidward want to get rid of the bunny.
After failing to attack the bunny, Squidward hides in a large carrot so he can call animal control so they can take the bunny. They come, but SpongeBob prevents them from taking the bunny and decides to raise it himself.
SpongeBob brings the bunny to his house and tries to feed it. However, since the bunny only wants vegetables, SpongeBob goes to the Barg'N-Mart to get something. While he's there, the bunny starts looking for food, only to make a mess in SpongeBob's living room. SpongeBob puts hot sauce everywhere to prevent the sea bunny from doing this again, but the bunny eats the hot sauce and causes fires around the room. Thankfully, SpongeBob stops the fires and prevents the bunny from burning anything else.
Later, SpongeBob tries to have the bunny live in a cage, but he does not want to live in it and hinds underneath the wallpaper of the walls. Afterwards, SpongeBob finds Patrick in his couch and asks him to get the bunny out, but he gets stuck in the wallpaper. SpongeBob decides to get a girl bunny from the store for the bunny to fall in love with, and this succeeds.
When the two sea bunnies go into the laundry basket, they start to multiply. SpongeBob and Patrick chase the bunnies until they end up reaching Squidward's house. The house gets completely flooded by bunnies, until the house itself gets destroyed and the bunnies form a look-alike house out of themselves. The episode ends with Squidward losing his sanity and turning into a bunny, while the animal control officer tries to capture him.

- This episode is available on the SpongeBob SquarePants Vol. 18 and The Complete Eleventh Season DVDs.
- This episode was paired up with "Moving Bubble Bass" during the original American airing, but since it has re-airing with "Sanitation Insanity."
- The shed from "The Curse of Bikini Bottom" is seen again at the end when all the bunnies ambush Squidward's house.
- In the real world, sea bunnies are a species of sea slug scientifically named Jorunna parva. They live in the Indian Ocean and in Papua New Guinea.
- Furthermore, one is depicted in the title card.
- Gary's toy ball from "Gary's New Toy" reappears on a shelf.
- Barg'N-Mart is called "Grocery" in this episode.
- A villain named Clam Head Candy Cad from "Mermaid Man and Barnacle Boy" makes a reappearance after nearly 19 years of absence by reappearing on a comic book cover.
- When Squidward is talking to the wooden dummy he says "Sacré bleu!" This translates to "Damn it!" in English.
- Bunny Wunny can be seen playing "Puka A" on his ukulele.
- In the real world, sea bunnies are hermaphrodites and would not need a partner to reproduce. This makes the bunnies depicted act more like actual rabbits instead.
- One of the paintings in Squidward's house is a spoof of The Scream.
- At the end of the episode, where Squidward goes insane and bounces around while wearing a straitjacket, it is a reference to Ripper Roo from the Crash Bandicoot series. Much like Squidward at the end of the episode, Ripper Roo is also insane, wears a straitjacket, and moves by bouncing around. When Squidward starts to go insane, he is even shown with Ripper Roo's eyes.
- The part where Squidward thinks he is a bunny is a reference to the Looney Tunes episode "Hare Brush," where Elmer Fudd is mentally ill and thinks he is a rabbit.
- When a sea bunny pulls out Squidward's mustache and makes it as banjo strings, it is a reference to Tom and Jerry episode "Pecos Pest," in which Uncle Pecos also pulls out Tom's whiskers as a string replacement every time his guitar strings snap.
- A picture of Gary can be seen when SpongeBob is in his home, but after getting groceries, a different picture appears in place of it.
- In the scene where Squidward puts his creation in the oven and kisses it, his back straps to his apron appear to be missing.
- When Patrick comes out from under the wallpaper, he is completely dark blue.
- When the sea bunny bites a piece of the table SpongeBob's flower is on, he spits dirt out of his mouth.
- Even though the sea bunny ate the hot sauce from all the items that SpongeBob poured on, SpongeBob still re-eats them, even though he couldn't re-pour it between frames, and even though he used a fire extinguisher.
