Worms

Worms are invertebrates with elongated, soft bodies. Though the earthworm is the most common, there are many varieties of worms, who in popular culture often have negative connotations, associated with "creepy crawlies" at worst, or with sour-flavored gummy candies at best. On Sesame Street, however, the worm is a much loved and vital species with an elaborate culture and society of its own.

Worms have appeared on Sesame Street as early as the first episode, in an animated segment to demonstrate the letter W. Early segments of this often referred to the worm as "yucky," feeding to the popular prejudice, and raising concerns from one conservationist.

For the most part, however, worms are presented in a very positive light, mostly in the person of Slimey, pet of Oscar the Grouch. Slimey is beloved by Oscar, well-liked by other residents, and proved popular with viewers. Later, Slimey's family was introduced, including baby sister Sloppy, parents Dusty and Eartha, and cousins Squirmy and Rachel. Other Grouches also have close relationships with worms. Grundgetta has Sylvia, and the participants in the Worm Summer Games each had their own Grouch trainer.

Worms have their own community, culture, and organizations, established through the labor of the worms themselves. They establish their own mass transit system in the form of a worm subway (Episode 3164) and band together to build a playground (Episode 3957). In addition, Slimey is a member of the Worm Scouts, a scouting troop, and all worms enjoy the annual Wormy Gras festival, the annelids' answer to Mardi Gras, and an ode to the joys of worminess.
