Wormy is a SpongeBob SquarePants episode from season two. In this episode, Patrick and SpongeBob take care of Sandy's pet caterpillar.





SpongeBob and Patrick are given the task of pet sitting Sandy's pets when she is out of town. One of Sandy's pets is a small monarch caterpillar named Wormy. Spongebob and Pat quickly befriend the caterpillar and they enjoy a day of play together, however; their fun is disrupted ; overnight, when Spongebob and Patrick are only at the Treedome, Wormy goes through quick metamorphisis and becomes a monarch butterfly. When they come back in the morning, Patrick and Spongebob think their new friend was eaten by the butterfly. They go breserk as they try to trap the "monster". Unfortunately, Wormy (now as a butterfly) manages to escape the Treedome while flying inside a bubble. Spongebob and Patrick begin to spread news of the terrible monster throughout Bikini Bottom. Mass chaos erupts and the whole town becomes destroyed and deserted.

Sandy arrives at the shattered town in a few days. She immediately finds Wormy and places him inside a jar. All the townsfolk cheer and celebrate the capturing of the monster.


  • SpongeBob: Gee, Patrick, I didn't know you spoke bird.
  • Patrick: No, that's Italian, SpongeBob.
  • Sandy: This here's my cricket. He's saying "hi" to you. Ain't he cute?
  • SpongeBob: Umm, sorry, I don't speak Italian.
  • SpongeBob (cheering like a cheerleader): YEAAAAAAH!!!
  • SpongeBob: We're in serious danger! There's a...a...a...a monster out there!
  • Mr. Krabs: Is he a paying customer?
  • SpongeBob: Oh, no Mr. Krabs, it doesn't want to eat Krabby Patties, it wants to eat you!
  • Patrick: Just like it ate Wormy!
  • Squidward: Ah, Wormy? SpongeBob and Patrick burst into tears. Well, if moron theater is over I think I'll just take a look at this. "monster". (sees butterfly) That's the monster?
  • Patrick: Pretty scary, huh?
  • Squidward: (Walks up to it with Mr Krabs) It's kinda cute.
  • Mr. Krabs: It reminds me of money!
  • SpongeBob: Ah! It ate them. And there it goes. 1st Wormy, then Squidward, later Mr. Krabs. That flying monster has eaten three friends too many, we must inform the citizens evil has surfaced .
  • SpongeBob: Okay Patrick this is a very delicate situation. It must be treated with great care and sensitivity.
  • Patrick: Gotchya! Patrick and SpongeBob start screaming. RUN EVERYBODY RUN A MONSTER!
  • SpongeBob: Remember Patrick, 2 vs 1 right? Patrick? Aaaaaaaaahh! It ate Patrick! (runs inside a barrel) Patrick, you're alive?
  • Patrick: I am?
  • Patrick: Really?
  • Patrick: Pet sitting? Isn't that gonna hurt them?
  • Spongebob: Until tommorow new best friend.


  • The close up of the butterfly is really the head of a buzzing horse-fly.
  • Wormy is able to complete the full transformation from caterpillar to butterfly in just one night. In real life this is impossible, and the length varies with different species if butterfly (in this case, Monarch butterflies, which is what Wormy was, spend ten to fifteen days in the chrysalis stage when changing into a butterfly.)
  • MY LEG: Fred runs out of his house after seeing the newscast.
  • The warning poster SpongeBob and Patrick put up depict a Viceroy butterfly, while Wormy is actually a Monarch butterfly. Viceroys belong to a different family group of butterflies, and are smaller and less common than the Monarchs. The reason why Viceroys resemble Monarchs is due to Müllerian mimicry, in which two separate species that share a certain predatory defense mechanism (in this case, being nasty-tasting to birds) also share very similar warning patterns.
  • This was the first episode to feature Patrick's new design, featuring thicker eyebrows, instead of the usual "Z" eyebrows.
  • Also, you can see a fireboat make a cameo in this episode when the city is on fire, its a unlockable boat inSpongeBob's Boating Bash.
  • When SpongeBob is saying "We did it, Patrick!" during the destruction scene, a meteor can be seen flying down until it falls offscreen in the background a few seconds later, a flash can be seen in the background, referencing the landing explosion.
  • This Is the 50th single episode.
  • There is a deleted scene about SpongeBob eating pie.
  • Some people recall the close up of the butterfly coming after Sandy says "I should get out of town more often".
  • At the beginning Patrick whistles, and SpongeBob says: "I didn't know you spoke bird!", and Patrick says "No, that's Italian". In the Italian version he says that it is Spanish.
  • 22nd episode with its title in it.
  • The Krusty Krab cash register boat is driveable as seen in this episode.
  • The title card is the same as Sandy's Rocket, but upside down.
  • The first episode to air in 2001 and the 21st century.
  • This is the first time SpongeBob sat for Sandy. Second was House Sittin' for Sandy .
  • The close-up of the horsefly could scare younger viewers.


  • In the end when Sandy is coming back, a bus stop sign is shown. Usually Bus Stops are not green and triangle shaped.
  • Though Wormy eventually pupates into a Monarch Butterfly, he looks nothing like a Monarch caterpillar.
  • At the part where SpongeBob and Patrick ran away from Wormy along with everyone else, the town is destroyed. But when they reach the stoplight while being chased, the town is perfectly fine.
  • When Patrick's helmet broke, acorns fell in it. The water should have been displaced and overflowed, but it stayed at the same level.
  • When SpongeBob and Patrick finally lead the butterfly outside, they only open the first door. There are two doors, so the butterfly should've stayed between them, instead of making its way outside.
  • Nancy's dress changes from yellow to gray in one point where the Bikini Bottomites are being chased by Wormy as butterfly.
  • When SpongeBob begs Wormy not to eat him, his mouth didn't sync right.
  • The mouse in the snake's digestive tract should be in the middle of the snake's body, not at the snake's tail.
  • Speaking of the snake, squirrels are much smaller than most snakes, so Sandy should have been dwarfed by her pet.
  • Snakes can eat squirrels, yet Sandy keeps one as a pet. In the same way, some people keep boas and pythons as pets, even though they're large enough to eat humans.
  • When Mr. Krabs and Squidward run away from Wormy, two pairs of underwear can be seen, but Squidward does not wear pants or underwear.
  • When Patrick is warning the other fish about the butterfly, his mouth does not sync up with the audio.
  • In the part of the episode where it shows people running away, there is one yellow fish flying.
  • When Patrick is with the people holding up SpongeBob and Sandy, he does not have his eyebrows. In another shot during the same scene, he does not have eyes.
  • In this episode while the bird is singing, apparently it's voice is the same to a European Robin in 2001 documentary nature film Winged Migration.
  • When Spongebob and Patrick trap the butterfly in the entrance of Sandy's treedome, Wormy somehow made it outside the front door and headed for the Krusty Krab.
  • When SpongeBob and Patrick first discover Wormy as a butterfly, they both run in different directions, but end up at the same table in the middle of Sandy's treedome.
  • The bubble that SpongeBob blows to catch the butterfly is impossible to make because he has his helmet filled with water on.
