Underworm

Underworms are a Muppet worm subspecies who appears in a 2009 episode of a popular preschool show, Sesame Street, and are similar to Carrie Underworm (a parody of a famous celebrity-turned-evil warlord, Carrie Underwood), appears at the Squirmadega Car Race and performs the Worm Anthem before the race begins, but during World War III, she became Carrie Underwood's assistant.

Soon after, Carrie Undrworm became the first tribal chief of the Underworm Tribe and soon, cloned herself and started up that tribe.

They are now friendly to humans, dylanuses, other Muppet subspecies, and other sapient species, except vampires, dragons, bonggambies and their allies due to bloody conflicts with them.
