Role in series[]
"Wormy"[]
When SpongeBob and Patrick are pet sitting for Sandy, they and Wormy play games such as hide-and-seek and tag. However, overnight, Wormy quickly metamorphoses into a butterfly. SpongeBob and Patrick return but naively believe the butterfly is a monster and ate Wormy when in reality it was Wormy. To save the town, SpongeBob and Patrick cause mass panic throughout and spread the news about Wormy all over town, all because the fish have never seen a butterfly before.
After Sandy returns from her trip and captures Wormy in a jar, the Bikini Bottomites celebrate, prompting Sandy to believe it was just because they missed her that much and she should leave town more often.
"Goons on the Moon"[]
Wormy is seen flying in space among asteroids and other pieces of junk.
"Escape from Beneath Glove World"[]
Wormy appears from episode's opening where he sits on a megaphone, but the commentator's shout blows his away.
Role in SpongeBob: Bubble Pop[]
He appears in the bubbles as when a player pops a bubble that contains Wormy, he will go around popping random bubbles.
Trivia[]

Poster of Wormy in The SpongeBob Movie: Sponge Out of Water (lower middle).
- In The SpongeBob Movie: Sponge Out of Water, a poster of Wormy in his butterfly form can briefly be seen in Sandy's treedome. The image of Wormy on the poster looks very similar to the one seen on the "Beware" fliers made by SpongeBob and Patrick.

- When Wormy's face is viewed as a close-up in butterfly form, a stock footage of a horse fly is used instead of an actual butterfly.
- This live-action insect footage used throughout the episode "Wormy" are all royalty-free, and owned by Oxford Scientific Films. All of the footage can be found on Getty Images.[1]
- The emerging butterfly footage was also used in Microsoft Encarta '95.[2]
- The infamous cleg fly close-up footage was also used in the Bill Nye the Science Guy episode "Insects."
- The live-action butterfly clips (i.e. when Wormy emerges and the news bulletin about the "monster" attacking) depict a female Monarch butterfly with thicker wing veins, compared to male Monarchs having thinner wing veins. This suggests Wormy may have actually been a female butterfly, as it is very hard to determine a Monarch caterpillar's gender until it metamorphoses into an adult butterfly (and thus Sandy assumed that the caterpillar was male).
- As mentioned above, when Wormy's face is viewed as a close-up in butterfly form, the wrong insect is shown. As Wormy is a butterfly, there are enormous, rainbow-colored, shimmering eyes and sharp mouthparts are seen, distinctive to that of a horsefly, instead of circular black eyes and a proboscis (tongue). Furthermore, butterflies do not make buzzing sounds, which (again) is a characteristic of flies.
- The episode "Wormy" was banned in some countries including Indonesia and Italy, due to Wormy's face being a cleg fly close-up frightening young viewers.[3]
- Wormy's close up became a popular internet meme and created a crossover video edits where other characters from other series reacting to Wormy.
- The word "wormy" means infested or eaten by worms.

- When Wormy is about to transform, he is depicted with a stock image of a caterpillar. The stock image of Wormy and the Chrysalis' were all edited to look green, in order to match the colors used for Wormy when he is animated.
