What is the name of Oscar the Grouch's pet worm?

What is the name of Oscar the Grouch’s pet worm? His pet worm is named Slimey.

Slimey is Oscar the Grouch’s pet worm on Sesame Street. The character is a small but memorable companion associated with Oscar’s trash-can home, adding a gentler friendship to the Grouch’s famously pessimistic world. Oscar may complain about nearly everything, but Slimey is one of his valued companions.

The answer is sometimes confused with other Sesame Street animal characters. Barkley is a dog, while Buster is Big Bird’s sheepdog. Oscar’s girlfriend is Grundgetta, but she is another Grouch rather than a pet. Slimey is specifically the worm.

Oscar and Slimey also illustrate how Sesame Street gives even its comic characters relationships and emotional contrasts. Oscar was created for the show’s street scenes alongside Big Bird, helping Muppets interact with the human cast. Slimey’s presence expands Oscar’s character beyond his familiar trash-can gag and grouchy catchphrases.
