Wormy is one of Sandy's pets who first appears in the episode of the same name. In the aforementioned episode, he matures from a monarch caterpillar into a monarch butterfly. He also appears in the books Wonderful Wormy, Salty Sea Stories, and Wormy, the GBA versions of the video games Revenge of the Flying Dutchman and Battle for Bikini Bottom, and the PS versions of SuperSponge and The Yellow Avenger.



As a caterpillar, Wormy is a light shade of green with black eyes and white spots.


As a butterfly, Wormy is dark orange with black stripes and black on the outermost parts of his wings; this design is that of a monarch butterfly.


At some point, Sandy bought or found him in Texas. Sometime later, she took Wormy to her home in Bikini Bottom.

He later turns into a butterfly overnight.

Role in episodes


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 and scares everyone in Bikini Bottom because they mistake him for a monster and 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 that she did not know she had been missed so much and should leave town more often.

"Goons on the Moon"

Wormy is seen flying in space among asteroids and other pieces of junk.
